WEBVTT 00:00:00.000 --> 00:00:07.000 Cool. What's up, Claude Plain? You guys might have noticed that we have a new screwdriver out and it did not take three years to make this time. 00:00:07.000 --> 00:00:11.000 That was due to a massive team effort from everybody involved. 00:00:11.000 --> 00:00:24.000 We thought it might be a cool exclusive if we talked about the design process and give you a bit more of a deeper dive into how we did it more than we did the screwdriver. 00:00:24.000 --> 00:00:31.000 There's a lot of work that actually goes into making a product and not all of it can make it into a YouTube video. 00:00:31.000 --> 00:00:38.000 Especially even though the screwdriver was, I think, 35 minutes long, there was a lot of stuff that had to be cut, 00:00:38.000 --> 00:00:46.000 A, from initial filming, B, in post, just because if we had all of it, it would have been a three, four, five-hour documentary. 00:00:46.000 --> 00:00:59.000 So this, while probably won't be four hours, will just give you kind of like the behind-the-scenes story behind the stubby and kind of how we took what was originally a three-year timeline 00:00:59.000 --> 00:01:07.000 and leveraged our experience from that timeline to make the new stubby come out way quicker. 00:01:07.000 --> 00:01:17.000 So, as with all good stories, it starts with the beginning and that beginning was the launch of the regular screwdriver. 00:01:17.000 --> 00:01:24.000 We were blown away by the success of the launch. 00:01:24.000 --> 00:01:37.000 You can watch my Meet the Team, which goes through kind of my view on it, and that's a pretty cool one to watch, not biased at all. 00:01:37.000 --> 00:01:41.000 But we were very blown away by the success of this. 00:01:41.000 --> 00:01:53.000 So much so that the months after the launch were basically just me 100% trying to stay on top of making sure manufacturing was going. 00:01:53.000 --> 00:02:04.000 We were getting the screwdrivers on time, that as many people would get their screwdriver before Christmas as possible, because we blew through all the waves. 00:02:04.000 --> 00:02:10.000 We had a plan, and then we sold out of the plan in a month, and I had to catch up. 00:02:10.000 --> 00:02:13.000 We had to catch up, and it was crazy. 00:02:13.000 --> 00:02:17.000 During that time, Herman came to us with an idea for the next project. 00:02:17.000 --> 00:02:31.000 Herman always thinking about the next project. Herman is the founder of Megapro, and kind of the brain behind a lot of the technology here in terms of ideation, 00:02:31.000 --> 00:02:37.000 and he's constantly looking for ways that we can take what we already have and make new tools from it. 00:02:37.000 --> 00:02:40.000 So I can't remember the exact time. 00:02:40.000 --> 00:02:45.000 It was probably around September, or comes after September. 00:02:45.000 --> 00:02:52.000 October? October. It was around there he came to us with this chungus. 00:02:52.000 --> 00:02:55.000 I don't know what size this is. What size is this? 00:02:55.000 --> 00:02:59.000 This is the biggest crap. What size is the paper? 00:02:59.000 --> 00:03:03.000 It's big. We have this big paper here. It's chungus size. 00:03:03.000 --> 00:03:10.000 It's the size I just invented. And this 3D print with an injection molded end cap. 00:03:10.000 --> 00:03:15.000 Right? And he said, this is the idea for LTT's stubby screwdriver. 00:03:15.000 --> 00:03:20.000 So if Arthur wants to pan around here and look at the chungus print, 00:03:20.000 --> 00:03:28.000 this basically is a cross section of a slim down version of our current screwdriver. 00:03:28.000 --> 00:03:33.000 We have the bit storage system for the stubby is going to only be six. 00:03:33.000 --> 00:03:41.000 Yeah. And then a slim down handle, which is just a squish trilobula design and a fixed shaft. 00:03:41.000 --> 00:03:45.000 Right? That was the plan. And this was the 3D model, which I have broken. 00:03:45.000 --> 00:03:51.000 Don't worry about it. So at the time we're like, cool idea, bro. 00:03:51.000 --> 00:03:54.000 But we have 99 problems and a new screwdriver. 00:03:54.000 --> 00:03:57.000 I hate one of them. If you cash my drip. Right? 00:03:57.000 --> 00:03:59.000 Like we were just trying to produce screwdrivers. 00:04:00.000 --> 00:04:05.000 Oh, and plus fixed shaft in a screwdriver wasn't really a plan for us. 00:04:05.000 --> 00:04:08.000 We're like, it has to be a ratcheting. Okay. 00:04:08.000 --> 00:04:11.000 And we were nervous that if we added a ratcheting, we just make it too long. 00:04:11.000 --> 00:04:16.000 But anyways, me, had even one free day in the middle of all of that, 00:04:16.000 --> 00:04:24.000 decided to just go like super low effort, like MVP prototype. 00:04:24.000 --> 00:04:27.000 I literally took a regular screwdriver. 00:04:28.000 --> 00:04:36.000 Changed out the shaft for just a ratchet gear and then press fit a 3D printed 00:04:36.000 --> 00:04:42.000 shafty boy on there and took a bandsaw and just one time chopped this thing in 00:04:42.000 --> 00:04:48.000 like roughly half. It's not straight because our bandsaw probably an old bandsaw by now because 00:04:48.000 --> 00:04:50.000 we would have gotten rid of it by the time stuff launches. 00:04:51.000 --> 00:04:59.000 I just sort it off and I remachine the, the shaft that holds the bit clip on. 00:04:59.000 --> 00:05:07.000 And we made a, it works, but it's, it's garbage prototype, which is kind of how 00:05:07.000 --> 00:05:13.000 we want our first MVPs to be. They meet the minimum requirements and they were quick to make that way. 00:05:13.000 --> 00:05:17.000 Linus can hold it and say, I hate it or I don't hate it. 00:05:17.000 --> 00:05:25.000 Linus didn't exactly hate it. But he didn't understand why we needed a stubby and it sat on ice for a while until 00:05:25.000 --> 00:05:36.000 megapro, oh it's in the box, sent us this, which was a little bit more of an effort 00:05:36.000 --> 00:05:43.000 of having a functional prototype. Basically it's literally the same ratchet with a shorter shaft. 00:05:44.000 --> 00:05:51.000 They did a really cool like machine steel ring for shattering of something we might do 00:05:51.000 --> 00:05:57.000 in the future and a properly working, you know, bit storage system. 00:05:57.000 --> 00:06:04.000 And we were like, this is cool. We could do a little bit better with the fit of the handle. 00:06:04.000 --> 00:06:09.000 I thought it was cool. Linus was like, eh, we don't need a stubby. 00:06:09.000 --> 00:06:11.000 I don't understand what the point of stubby is. 00:06:12.000 --> 00:06:18.000 Enter the NERG FORGE PC where he was trying to do, I think it was hard line water tubing 00:06:18.000 --> 00:06:24.000 and he was like, I cannot screw this thing in with the Chungus boy because he was trying 00:06:24.000 --> 00:06:29.000 to do it at 90 degree. I'm like, I have a solution. 00:06:29.000 --> 00:06:35.000 I ran and got this and an M6 bit and I think it might have made an appearance in that video 00:06:35.000 --> 00:06:42.000 although don't quote me on that. At that point he greenlit the project and I was like, cool, I have no time. 00:06:42.000 --> 00:06:46.000 I'm going to hire someone to take care of it for me, right? 00:06:46.000 --> 00:06:53.000 So we entered Rob and Rob armed with the knowledge that we had from launching this screwdriver 00:06:53.000 --> 00:06:58.000 and a bunch of new equipment that I think we did an exclusive on. 00:06:58.000 --> 00:07:07.000 I think we did a tour. But the SLS machine, his goal was like literally, it was like a trial by fire. 00:07:07.000 --> 00:07:14.000 I was like, here's what I have, which was nothing at the time other than like the models for this. 00:07:14.000 --> 00:07:17.000 Here's the goal of four inches. 00:07:17.000 --> 00:07:20.000 You need to make this four inches. 00:07:20.000 --> 00:07:24.000 Here's some inspiration of what I've done in the past. 00:07:24.000 --> 00:07:33.000 Okay. So can you tell the people how we went from that, which is basically 3D printed prototypes 00:07:33.000 --> 00:07:39.000 to what I call the final prototype before we approved tooling? 00:07:39.000 --> 00:07:43.000 Because at this stage of filming right now, this is probably... 00:07:43.000 --> 00:07:49.000 So the date right now is like, we're coming up to April and we have just approved tooling 00:07:49.000 --> 00:07:53.000 and currently the goal is to meet LTX. 00:07:53.000 --> 00:07:57.000 We will see in the future if we meet that or not. 00:07:57.000 --> 00:08:03.000 But we've had this for like a couple of months now and tooling's been well underway for a while. 00:08:03.000 --> 00:08:10.000 So I don't know, why don't you walk the people through kind of like, you started a new job. 00:08:10.000 --> 00:08:13.000 You had this like goal. 00:08:13.000 --> 00:08:22.000 How did you... Like what is your thought process? What is your kind of prototyping like methodology to go from essentially what is like... 00:08:22.000 --> 00:08:31.000 Yes, we made one. It looks cool, but there are some issues that Linus had to this is literally what we're going to launch. 00:08:31.000 --> 00:08:40.000 Just injection molded. So when we started out, like Kyle was saying, I got the design files for our full size screwdriver 00:08:40.000 --> 00:08:47.000 and then some of these prototypes. So we got the one that Megapro was working on that had pretty much the functionality that we're looking for 00:08:47.000 --> 00:08:50.000 in terms of the bit clip and the bit storage. 00:08:50.000 --> 00:08:54.000 But I think like how I mentioned, we wanted to tweak maybe the fit of the handle a little bit. 00:08:54.000 --> 00:09:01.000 And then there was the one that we built internally, you know, in an afternoon, they basically cut down the full size one. 00:09:01.000 --> 00:09:08.000 So kind of armed with that, I started poking around the CAD model, flying around and figuring out which parts can we keep the same. 00:09:08.000 --> 00:09:14.000 So we can kind of minimize the number of new molds we're making, the new parts we're ordering and then which parts do we have to change 00:09:14.000 --> 00:09:20.000 just to make sure that when we build our little tiny version, we get the amount of access that we need to get all the bits out 00:09:20.000 --> 00:09:27.000 while still keeping, you know, as many of the molds the same between the full size and the stubby as we can. 00:09:27.000 --> 00:09:36.000 So in terms of what parts we can keep the same, I started taking a look at how do we start getting just enough opening 00:09:36.000 --> 00:09:42.000 that we can comfortably get bits in and out of here without needing to change every single part. 00:09:42.000 --> 00:09:46.000 So that was basically pretty straightforward with the CAD model. 00:09:46.000 --> 00:09:53.000 You can start figuring out what components interact with each other when they're open, which components interact with each other when they're closed. 00:09:53.000 --> 00:10:01.000 And then we can start seeing, is there enough in here to simply take what is our original ratchet mechanism 00:10:01.000 --> 00:10:05.000 if we could keep everything the same and just make this shorter, could we make it work? 00:10:05.000 --> 00:10:10.000 So after a couple of weeks of playing around, we figured out something here needs to shrink 00:10:10.000 --> 00:10:15.000 to make sure that obviously if you look here, if we just stuck our full size ratchet inside our stubby, 00:10:15.000 --> 00:10:19.000 half of the handle would just be the zinc part of this mechanism. 00:10:19.000 --> 00:10:27.000 Notice this one is way longer in the throat to account for that length, right? 00:10:27.000 --> 00:10:36.000 And like another side note here is if you shorten this, how badly does it affect your ability to can out the actual mechanism 00:10:36.000 --> 00:10:40.000 from the plastic, which was another consideration. 00:10:40.000 --> 00:10:45.000 So we started playing around and figuring out how much can we shorten it while keeping enough strength 00:10:45.000 --> 00:10:55.000 so the handle doesn't just twist right off the screwdriver. So my first prototype started off with our full size, so this is the same size of the ratchet housing that goes inside our full size screwdriver. 00:10:55.000 --> 00:11:02.000 So the first couple of times I tried it, I just 3D printed a little fixture so that we could throw this into our CNC machine 00:11:02.000 --> 00:11:09.000 and start cutting it down and figuring out how short do we need to go to make it fit inside a form factor that looks like this. 00:11:09.000 --> 00:11:17.000 So after a bit of playing around, kind of decided on how short do we make the zinc, how much do we need to shorten the shaft that goes into it. 00:11:17.000 --> 00:11:27.000 And then once we had that figured out, we can start putting out some orders to our suppliers to get kind of a more proper prototype of this zinc. 00:11:27.000 --> 00:11:36.000 So when we were figuring out how we wanted to go about that, one design was basically the same as our current design, just miniature. 00:11:36.000 --> 00:11:44.000 So you can see we took the zinc and cut it a little shorter, we took the shaft and cut it a little shorter, and it's the same design where the shaft is pressed in. 00:11:44.000 --> 00:11:53.000 Now in part of that discussion when we started to talk with our suppliers, they know a lot more about the details and the capabilities of their different manufacturing processes. 00:11:53.000 --> 00:12:03.000 One of them actually recommended, since this is a little bit smaller, what about building in that shaft into the same casting as the main housing? 00:12:03.000 --> 00:12:10.000 So that's another part that we actually tried. So now we've got some samples of both designs, one where a shaft is pressed in, the same as our current design, 00:12:10.000 --> 00:12:16.000 and another one that we're trialing, which is recommended by our supplier, which is integrating that into one casting. 00:12:16.000 --> 00:12:23.000 So that actually helps us in terms of supply chain and assembly because we removed an assembly step, we removed a part. 00:12:23.000 --> 00:12:30.000 So now when we get this zinc part from our casting supplier that already has that shaft pressed in, we can save that step. 00:12:30.000 --> 00:12:39.000 So that was in terms of how we had to modify the ratchet material, the ratchet housing design rather, and then we kind of go into how do we tweak the fit of the handle. 00:12:39.000 --> 00:12:49.000 So that's something that we were able to do pretty easily in-house. So we went, we started testing with, we do our standard kind of fused filament 3D printing. 00:12:49.000 --> 00:12:56.000 So we started testing this on some of our bamboo printers that we have in-house. The speed on those printers let us basically iterate these every couple of hours. 00:12:56.000 --> 00:13:07.000 We can test a new shape. And then once we kind of settled in on something that was comfortable to use, we wanted to address how do we get something that's strong enough that we can actually start driving this screwdriver every day 00:13:07.000 --> 00:13:17.000 without the handle just eventually cracking apart. So then we started going into kind of a prototyping method that gets us closer to a production material. 00:13:17.000 --> 00:13:29.000 This is off of our SLS machine out of nylon 12. A laser actually melts layers of fine nylon powder together and gets a very, very similar final product to injection molding. 00:13:29.000 --> 00:13:37.000 The real only difference that we've been noticing so far is a little bit of this surface finish. I don't know if you can see from here, but you see a little bit of layer lines. 00:13:37.000 --> 00:13:44.000 That's just based on the resolution of the laser and the layers of powder in the part. 00:13:44.000 --> 00:13:52.000 And then from there we started putting together little testing prototypes. We're tweaking some of the tolerances here to get just enough opening. 00:13:52.000 --> 00:13:57.000 Some versions we had, you know, one or two millimeters difference here and we're getting some issues with access. 00:13:57.000 --> 00:14:06.000 So once we got that dialed in, we're basically ready to order the design of the ratchet that we're looking for and the handle shapes that we're looking for. 00:14:06.000 --> 00:14:15.000 In terms of some of the other changes that we had to make between the full size driver and the stubby driver, some of the parts we had to change were actually, if we look at this picture here, 00:14:15.000 --> 00:14:23.000 this red piece is part of Megapro's great design that gets us that snappy feel. 00:14:23.000 --> 00:14:30.000 So that feel right when it closes, that snap is something we wanted to make sure we transferred over from our full size driver. 00:14:30.000 --> 00:14:38.000 But unfortunately this part needed to shorten a little bit to fit inside the length of this handle. 00:14:38.000 --> 00:14:42.000 So one of the things that we ended up having to try... 00:14:42.000 --> 00:14:48.000 There's the new one. I'll find an old one for you. 00:14:48.000 --> 00:14:54.000 So because this got shorter, there's a spring inside this part that also had to get shorter. 00:14:54.000 --> 00:15:02.000 And when we start changing the length of the spring, that was starting to change the feel of how snappy this end cap would be. 00:15:02.000 --> 00:15:09.000 So another thing that we were testing out, a whole bunch of different test springs. 00:15:09.000 --> 00:15:24.000 We changed the diameter of the spring basically to adjust how much force there was to try and get the fit and the feel of the new shorty pin to be the same feel as our full size pin. 00:15:24.000 --> 00:15:29.000 So you can see here my quick and dirty method of making sure that the forces are similar to each other. 00:15:29.000 --> 00:15:39.000 Since we don't have a setup right now that lets us do force measurement on pushing and pulling this, I just kind of hot glued one of our prototypes together. 00:15:39.000 --> 00:15:47.000 This is our standard screwdriver. And then I kind of hot glued one with this new stubby pin inside it. 00:15:47.000 --> 00:15:53.000 And then we can swap out the springs and we kind of trial it so that the forces are pretty much the same. 00:15:53.000 --> 00:16:00.000 We've got to compare, we were noticing some of them, if the spring is too weak, this would just move every time and this end cap wouldn't even move. 00:16:00.000 --> 00:16:06.000 If it's too stiff, we're basically seeing the opposite where the full size driver was moving in and out and this side wasn't moving at all. 00:16:06.000 --> 00:16:15.000 So this is one way that we're, you know, rather than going through all the details of calculating the spring force, because at the end of the day what we're going for is we want that end cap to feel good. 00:16:15.000 --> 00:16:18.000 We just put it together and figured out what felt the same. 00:16:18.000 --> 00:16:30.000 We did use some elementary spring equations to guesstimate the ballpark, but fine tweaking is all done by feel. 00:16:30.000 --> 00:16:40.000 Considering the spring isn't mission critical if you get it like a hair on, but it's more, it's easier to define the spring in terms of feel. 00:16:40.000 --> 00:16:45.000 We're at stands right now and at this point in time just to ballpark it. 00:16:45.000 --> 00:16:49.000 So I think there's three molds that we're making right now. 00:16:49.000 --> 00:16:59.000 So obviously the handle changed. So what you can expect out of the, this is me talking in the past, exactly the same ratchet. 00:16:59.000 --> 00:17:08.000 So like the same, the same like torque, the same like back torque, like ratcheting torque is like super, super low. 00:17:08.000 --> 00:17:16.000 Like if you've ever used the regular screwdriver, you know that in most cases you can just like ratchet through a machine screw. 00:17:16.000 --> 00:17:20.000 So it's literally the same mechanism. 00:17:20.000 --> 00:17:28.000 Functionally, we found that shortening this doesn't cause the ratchet to fail by camming out the plastic. 00:17:28.000 --> 00:17:32.000 There's other parts in the ratchet that will fail before that. 00:17:32.000 --> 00:17:47.000 Having the zinc on here adds no perceivable difference to like how smoothly it goes in and out, which is great for the reasons that Robert had mentioned in terms of like economies of scale and stuff. 00:17:48.000 --> 00:17:54.000 Right. So molds that we're redoing is the handle, which is this guy. 00:17:54.000 --> 00:18:01.000 Again, these are all the SLS molds that we do, SLS plinths that we do before we do an injection mold. 00:18:01.000 --> 00:18:10.000 It's kind of our best method for doing like a, how do you say it, like a, just a sanity check of kind of our design. 00:18:10.000 --> 00:18:18.000 Cause anyone who's designed a product, there is what works in the model and then there's what works in real life. 00:18:18.000 --> 00:18:23.000 Sometimes there's differences that you have to account for. 00:18:23.000 --> 00:18:29.000 So having something physical that you can test and also give to Linus, who's going to incidentally show it on camera. 00:18:29.000 --> 00:18:39.000 Also, like just get excited about it on his own terms and having something that's like, like robust enough that it's not going to break. 00:18:39.000 --> 00:18:44.000 From that, cause he dropped stuff like that will still work. 00:18:44.000 --> 00:18:51.000 If I bother finding it, right? So that's why we do like doing it out of the SLS. 00:18:51.000 --> 00:18:58.000 We find that the resin stuff is really good for exterior finish because it's nice and smooth because it has way better resolution. 00:18:58.000 --> 00:19:04.000 But unless we go to like a very rigid material, it's very brittle. 00:19:04.000 --> 00:19:07.000 And even rigid materials brittle as well. 00:19:07.000 --> 00:19:11.000 So press fits and stuff just don't feel right. 00:19:11.000 --> 00:19:18.000 Plus it's a completely different chemistry. Nylon 12 is part of what makes up the polymer that we use to make this, right? 00:19:18.000 --> 00:19:28.000 So this is an ABS nylon polymer. So, you know, it gives us some reliable properties, like especially in terms of shrinkage. 00:19:28.000 --> 00:19:33.000 And yeah, so we're making a handle. We're making a tube and we're making this little piece. 00:19:33.000 --> 00:19:37.000 So the three molds that we're making, except this is going to be out of Delrin, not nylon. 00:19:37.000 --> 00:19:40.000 Cause Delrin has better mechanical properties. 00:19:40.000 --> 00:19:43.000 If you're doing motion, you generally want Delrin. 00:19:43.000 --> 00:19:47.000 Delrin, we make the bit clips out of Delrin. 00:19:47.000 --> 00:19:51.000 This is still that nylon ABS polymer, so triax. 00:19:51.000 --> 00:19:55.000 And then this is Delrin and that does all the motion. 00:19:55.000 --> 00:19:58.000 So those are the three molds we're making. 00:19:58.000 --> 00:20:02.000 And then we're leveraging our end cap is the same. 00:20:02.000 --> 00:20:08.000 Our bit clip is the same. And our selector ring and all the ratchet components are the same. 00:20:08.000 --> 00:20:12.000 And the only thing that we had to remake from the ratchet is the whole housing itself. 00:20:12.000 --> 00:20:17.000 So at this point, what we're doing is we have this sample. 00:20:17.000 --> 00:20:24.000 So we built a couple of ratchets and, you know, that's what this is. 00:20:24.000 --> 00:20:27.000 It's got the new ratchet housing in there. 00:20:27.000 --> 00:20:32.000 So end caps are the same. Select is the same. All the internal ratchet components are the same except this. 00:20:32.000 --> 00:20:35.000 The shaft is obviously different, but that's just a machine part. 00:20:35.000 --> 00:20:40.000 Same strong magnet. Like we compromise on nothing, right? 00:20:40.000 --> 00:20:43.000 Like you still have the same magnet bit. It fits the same bit. 00:20:43.000 --> 00:20:52.000 So if you already have an LTT screwdriver and you're rocking like a bunch of extra bit sets, like torques and stuff, it's just going to fit. 00:20:52.000 --> 00:20:59.000 So unfortunately, not unfortunately, just because of physics, we're limited to six bits, right? 00:20:59.000 --> 00:21:03.000 Like half a bit load there. But you know, throw your six common bits in there. 00:21:03.000 --> 00:21:09.000 Like if you do like hard line water cooling, throw a couple of hexes, maybe some flats and Phillips two in there. 00:21:09.000 --> 00:21:13.000 And now you've got a mini boy. Same torque, same ratchet feel. 00:21:13.000 --> 00:21:18.000 So like you want to crank this, it's just going to depend on how strong your fingers are. 00:21:18.000 --> 00:21:23.000 Yeah, but that's basically the story behind like this initial portion. 00:21:23.000 --> 00:21:28.000 Hopefully it's going to be done by LTX. 00:21:28.000 --> 00:21:33.000 We'll see. But by the time this releases, we will know. 00:21:35.000 --> 00:21:38.000 Hey, welcome back. I think it's been a couple of months since you've been over here. 00:21:38.000 --> 00:21:42.000 Yeah, since then it's been exciting. We've gotten some injection molded parts. 00:21:42.000 --> 00:21:45.000 These are the first samples that we got for the actual injected parts. 00:21:45.000 --> 00:21:51.000 So last time we were still working with these SLS 3D printed parts from our in-house 3D printer. 00:21:51.000 --> 00:21:55.000 Now we've got the actual injected molded parts out of the actual material. 00:21:55.000 --> 00:21:58.000 So that's the tube inside. 00:21:58.000 --> 00:22:03.000 And then we've also got this tanning pin. Last time we were talking about the nylon part. 00:22:03.000 --> 00:22:07.000 And here's that actual part out of Delrin, acetyl material. 00:22:07.000 --> 00:22:14.000 So we've had a chance to put all that together and start getting a feel for how the real sliding action for this screwdriver is going to go. 00:22:15.000 --> 00:22:22.000 So if we look close up in here, we can see way in here we're using the actual injected tube piece. 00:22:22.000 --> 00:22:25.000 And then it's also riding against that actual injected tanning pin. 00:22:25.000 --> 00:22:30.000 So now it's just as smooth as our full-size screwdriver. 00:22:30.000 --> 00:22:36.000 Exactly the same snappy action. And then now we can finally get some approvals going on those injected molded parts. 00:22:36.000 --> 00:22:40.000 And also the spring inside that gives it that snappy feeling. 00:22:40.000 --> 00:22:43.000 The handle here is that dark gray color is still a nylon one. 00:22:43.000 --> 00:22:50.000 So that's the last mold in a couple of weeks. We're going to get that and then hopefully get everything approved and get this production on the go. 00:22:50.000 --> 00:22:57.000 We can also see here when we get our first samples, we did some work in the shop. 00:22:57.000 --> 00:23:03.000 We cut some of them in half. We cut some angles off just so we can get some good measurements on the inside to make sure the dimensions are all accurate. 00:23:03.000 --> 00:23:07.000 The one thing about injection molding is you can design it all perfect in CAD. 00:23:07.000 --> 00:23:11.000 But there's a little bit of black magic going on in the mold makers when they got to figure out 00:23:11.000 --> 00:23:15.000 how much the plastic is going to shrink and warp and stuff when it all gets injection molded. 00:23:15.000 --> 00:23:19.000 So we just make sure we cut it apart, make sure everything fits right. 00:23:19.000 --> 00:23:27.000 Here's another example of how we're testing. So this one we obviously just stick that end cap on and we make sure that these barbs, 00:23:27.000 --> 00:23:30.000 when we press it in, we need to make sure that they're fitting properly. 00:23:30.000 --> 00:23:33.000 They have the right amount of holding force and they're sitting in the right place. 00:23:33.000 --> 00:23:37.000 Ratchet is so much smaller. Yeah, it's a real small one. 00:23:37.000 --> 00:23:42.000 Let's see if we have a, I guess this is one that we just have again on the full size one. 00:23:42.000 --> 00:23:45.000 But you can imagine that's the difference here. Wow. 00:23:45.000 --> 00:23:48.000 But it feels basically the same. Yeah, yeah. 00:23:48.000 --> 00:23:51.000 The one thing we're shooting for when we get that feel almost exactly the same. 00:23:51.000 --> 00:23:54.000 You know, same going for that comfort in the hand, 00:23:54.000 --> 00:23:58.000 whether you want to hold it way at the end, choke it up tight, something like that. 00:23:58.000 --> 00:24:01.000 That's something we're tweaking a lot to make sure that it feels comfortable. 00:24:01.000 --> 00:24:06.000 That snappy action is feeling comfortable and then it's going to be just as fidgety as our big one. 00:24:06.000 --> 00:24:09.000 Between the last time that we saw the stubby screwdriver now, 00:24:09.000 --> 00:24:12.000 were there any challenges that came up along the way? 00:24:12.000 --> 00:24:17.000 Nothing major from then to now. We're kind of tweaking maybe some of the detail tolerances and things like that. 00:24:17.000 --> 00:24:21.000 So some of the things we're looking at, for example, as we put this all together, 00:24:21.000 --> 00:24:26.000 you can imagine when this is closed, you know, we're not talking about tons of space on the end here. 00:24:27.000 --> 00:24:32.000 So we're tweaking where we can deal with the tolerance stack up where we can buy some space, 00:24:32.000 --> 00:24:37.000 make sure that we can fit the same bit clip inside. 00:24:37.000 --> 00:24:41.000 Oh, here this guy. Same bit clip we can hold those six bits, 00:24:41.000 --> 00:24:45.000 make sure it can come out far enough that we can comfortably get the bits. 00:24:45.000 --> 00:24:50.000 I think some of our early prototypes, I don't know if we have one here, but some of the early ones were kind of stuck with them opening just like that. 00:24:50.000 --> 00:24:56.000 And it kind of made it a little difficult to get out. So the last two or three millimeters is something that we had to fight a little bit for, 00:24:56.000 --> 00:25:03.000 figure out where we can buy some space, and still make sure that, you know, things like the barb on the end here 00:25:03.000 --> 00:25:07.000 have enough meat to hold on to this guy when we press it on. 00:25:07.000 --> 00:25:11.000 You can imagine there's, you know, that's all that we have holding on there. So we got to make sure we have the right dimensions there 00:25:11.000 --> 00:25:14.000 to make sure everything's pressing in and holding tight. 00:25:14.000 --> 00:25:20.000 Another big change that we worked on since last time we talked, previously we were just looking at a standard smooth shaft on the end. 00:25:20.000 --> 00:25:24.000 We're doing some testing and we kind of found if you're kind of choked up tight 00:25:24.000 --> 00:25:28.000 and you're trying to turn the screwdriver there and you're, 00:25:28.000 --> 00:25:31.000 let's say you're choked up right against the surface, it can be a little slippery. 00:25:31.000 --> 00:25:35.000 So we're actually doing some testing and adding that same sharp knurling 00:25:35.000 --> 00:25:41.000 that we have on the full-size screwdriver. We basically slapped that same diamond knurling on the tip of the stubby. 00:25:41.000 --> 00:25:45.000 And that way, if you're choked up real tight, you need to get started with a screw or something like that. 00:25:45.000 --> 00:25:49.000 You just get a little bit more grip. You're not slipping around on the shaft there. 00:25:51.000 --> 00:25:58.000 Look what we got. These are the handles. We did a trip to pH molds yesterday and we got some samples of the last part 00:25:58.000 --> 00:26:03.000 we're waiting for for the stubby screwdriver. So we got all of these sample handle shots. 00:26:03.000 --> 00:26:09.000 Oh wow. And you can see in here, we even have our first official real stubby. 00:26:09.000 --> 00:26:12.000 So this is the first one we built with all injection molded parts. 00:26:12.000 --> 00:26:15.000 Wow. The handles, the last guy that we picked up yesterday. 00:26:15.000 --> 00:26:20.000 So now we got this big box of parts. We're doing some last sample testing, last prototypes. 00:26:20.000 --> 00:26:26.000 Make sure everything's good to go. And then see if we can get a box of these ready to get into everyone's hands at LTX. 00:26:26.000 --> 00:26:29.000 So this right here is what you'll be able to expect when you buy one. 00:26:29.000 --> 00:26:33.000 Exactly. So this is basically what it's going to look like when we order it. 00:26:33.000 --> 00:26:36.000 I think we're doing the orange and black with the silver shaft 00:26:36.000 --> 00:26:40.000 and the black and black with the silver shaft. 00:26:40.000 --> 00:26:46.000 I think we may also be doing a limited run of orange and black end caps with the black shaft. 00:26:47.000 --> 00:26:53.000 So that might be something to look out for. I think we still have some last technical details to work out and see if we're going to make that happen. 00:26:53.000 --> 00:26:56.000 But I think we might have some for the black shaft fans out there. 00:26:56.000 --> 00:26:59.000 So walk me through why this took a little bit longer. 00:26:59.000 --> 00:27:04.000 Yeah. So there's a couple of rounds of back and forth for all of these different parts that were injection molding. 00:27:04.000 --> 00:27:07.000 So the last mold we were waiting for were these handles. 00:27:07.000 --> 00:27:12.000 So we went by yesterday to our injection molder, picked up obviously this sample batch, 00:27:12.000 --> 00:27:17.000 but they were pointing out some things that you basically don't know until you start shooting some mold, 00:27:17.000 --> 00:27:22.000 some little intricacies of what makes injection molding such an art. 00:27:22.000 --> 00:27:27.000 So one of the things they pointed out yesterday and they provided us with some samples here that they have labeled, 00:27:29.000 --> 00:27:33.000 because as you can see with this part here, 00:27:33.000 --> 00:27:38.000 so in the injection molding machine, the plastic gets shot into a nozzle on this end. 00:27:38.000 --> 00:27:46.000 This is called the sprue. It hits the runner system, it spreads out, and then these two parts are made out of one injection. 00:27:46.000 --> 00:27:50.000 So obviously with one shot coming in, the plastic is injecting here, 00:27:50.000 --> 00:27:53.000 and then it's splitting out into two different handles. 00:27:53.000 --> 00:27:58.000 They were noticing some basically balance issues with how the plastic were flowing into the two halves. 00:27:58.000 --> 00:28:01.000 So you can see here they did a little bit of a circle. 00:28:01.000 --> 00:28:06.000 We have some marks that are showing up in the final part. 00:28:06.000 --> 00:28:10.000 This one they were saying is a result of some gas getting trapped in the mold, 00:28:10.000 --> 00:28:14.000 and that's because this particular mold on the first test, 00:28:14.000 --> 00:28:20.000 for some reason one of the halves of this mold, so one of the handles is filling a little bit faster than the other one, 00:28:20.000 --> 00:28:23.000 and that's just causing an imbalance in the way the plastic flows through. 00:28:23.000 --> 00:28:28.000 So they were actually able to work through troubleshooting that a little bit for us because 00:28:28.000 --> 00:28:32.000 our partners know that we're trying to get everything out to you guys for LTX, 00:28:32.000 --> 00:28:36.000 so we found a workaround here, and they provided a sample of that as well. 00:28:36.000 --> 00:28:39.000 You can see here they labeled this a workaround. 00:28:39.000 --> 00:28:45.000 So rather than changing the mold for this batch, they actually just changed the parameters for how they're running the injection molding machine. 00:28:45.000 --> 00:28:49.000 That helps get rid of the mark that we were seeing, so you can see here they're not circling anything, 00:28:49.000 --> 00:28:54.000 we've got these really almost invisible parting lines as you wear the two parts of the mold separate. 00:28:54.000 --> 00:29:01.000 But the trade off for that is that this shot with these modified parameters to make those marks go away 00:29:01.000 --> 00:29:06.000 takes a little bit longer to shoot. So obviously that means if you're taking longer to shoot your handles, 00:29:06.000 --> 00:29:11.000 you can't produce parts as fast, and at the end of the day that means somebody is incurring some cost somewhere. 00:29:11.000 --> 00:29:16.000 So I think right now the plan is we're going to try and get this workaround running 00:29:16.000 --> 00:29:19.000 for a smaller number than our initial original order, 00:29:19.000 --> 00:29:24.000 get some parts out so everybody can get some on hand for LTX for the initial release, 00:29:24.000 --> 00:29:27.000 and then once we get a first run going, 00:29:27.000 --> 00:29:32.000 then we're going to see if we can find a workaround that actually modifies the mold a little bit to solve that problem. 00:29:32.000 --> 00:29:35.000 Can we see a little bit of how the stubby screwdriver actually looks? 00:29:35.000 --> 00:29:40.000 Yeah, for sure. So if you remember last time I think we were looking at this prototype guy, 00:29:40.000 --> 00:29:49.000 so we were looking at pretty much still everything injection molded except our handle was still out of our SLS nylon machine, 00:29:49.000 --> 00:29:55.000 so that's a laser-centered nylon powder. So the last part that we picked up yesterday is this handle here. 00:29:55.000 --> 00:30:01.000 So now we've got all parts injection molded, the same surface finish that we get on our large screwdriver, 00:30:01.000 --> 00:30:08.000 so we're going to get the same sort of like a satin, semi-smooth, semi-shiny finish I guess. 00:30:08.000 --> 00:30:14.000 And I think we mentioned in our last update, we did decide to go with a knurled shaft there, 00:30:14.000 --> 00:30:20.000 so in case you need to do a little bit of tightening directly using the shaft, 00:30:20.000 --> 00:30:24.000 you get a little bit more grip there. How do you think it came out? 00:30:24.000 --> 00:30:28.000 I think it turned out great. I think it feels really good. 00:30:28.000 --> 00:30:32.000 The handle was the last part that we're waiting for and obviously it's one of the biggest parts you look at, 00:30:32.000 --> 00:30:35.000 the biggest part you feel when you're using the screwdriver. 00:30:35.000 --> 00:30:39.000 So Kyle and I did a stop-by yesterday and we were super stoked with how this came out. 00:30:39.000 --> 00:30:45.000 The finish is really good. I think I was mentioning here, you can see these lines, you can barely see it. 00:30:45.000 --> 00:30:49.000 That's actually where the two halves of the mold separate, so one on that side, one on this side. 00:30:49.000 --> 00:30:53.000 Our mold makers that we're working with do a really good job making that almost invisible. 00:30:53.000 --> 00:30:56.000 You can barely feel it when you run your finger over, you're going to feel a little bit. 00:30:56.000 --> 00:30:59.000 That's kind of the nature of injection molded plastic. 00:30:59.000 --> 00:31:02.000 But yeah, this came out really good. 00:31:02.000 --> 00:31:09.000 So we're doing this. Obviously with the test, we're doing some last-minute checking to make sure we're going to build a handful more of these. 00:31:09.000 --> 00:31:15.000 Make sure when we press this ratchet assembly, it actually presses into the hole on the end of the screwdriver here. 00:31:15.000 --> 00:31:22.000 So that is a press fit. If you guys have seen the video where we explained how we build our standard screwdriver, 00:31:22.000 --> 00:31:29.000 I think Linus and Kyle are actually at pH molds where they're shooting the handles and then pressing in that ratchet assembly. 00:31:29.000 --> 00:31:32.000 This is the same idea, just everything's a little bit smaller. 00:31:32.000 --> 00:31:38.000 So we're making sure that this dimension here, when we press that ratchet assembly in there, it stays nice and tight. 00:31:38.000 --> 00:31:41.000 It stays connected properly for the life of the screwdriver. 00:31:41.000 --> 00:31:44.000 So we're looking all good to launch for LTX? Yeah, we're looking pretty good. 00:31:44.000 --> 00:31:47.000 We're doing a last set of measurements, obviously. 00:31:47.000 --> 00:31:50.000 We picked these up yesterday, so there's still a couple of days of testing to go. 00:31:50.000 --> 00:31:54.000 But all signs look like we're going to get a batch of these out for LTX.
