 Today, I'm going to take these 3D printed pieces. Today, I'm going to take these 3D printed pieces and make a bridge. My name's Jim and this is the Edge of Tech. So like I said, today we're going to take all of these pieces here that I 3D printed and this white PLA filament, we're going to make a bridge. Now I am using just a cheap white 3D printed filament that came in one of the 3D printers that I unboxed. I'm not sure which one, but it's white and I thought the contrast would stand out against the orange. Now the pieces themselves were 3D printed on a Prusa Mini and I just designed this quickly in Tinkercad. These pieces are just a rectangle with two holes, one on each side so you can string filament through there to create yourself a rope bridge. What you might not know is that on that side of my garage I'm actually building a 1.24th scale rock crawler course. Now this is just for our little 1.24th scale trucks and we're going to have a little fun crawling around on it. So far it's been super fun to build. It's time to add a couple of bridges. Now what I don't know is how long this PLA is going to hold up. I know that it gets brittle and cracks over time so I have a feeling it's not going to last forever and if I'm driving on it and it breaks it's going to cause a glorious crash. Let me show you how I think this is going to work. So my plan is to take the course, bring it over here onto the bench, then I'm going to measure the gap between the space that I need the bridge. Take some planks like this, take a piece of filament like this, again this is just white PLA that I got in one of the printers. And then what I'll do is each plank has a hole like this in it on each side, one here and one here. These holes are 2mm thick and this filament is 1.75mm thick so this will just fly through just like that. Once I get all of the planks on one side I'll go back and do the other side and in the end it'll create a bridge. Now the cool thing about this bridge is that we'll be able to curve it if we want because you can curve the filament. You'll be able to make the bridge planks closer or farther apart depending on how far you want it and how the tires work. We don't want this too easy but we also don't want it impossible. So the cool thing is we can do whatever we want. But I think what we need to do first is get the course on the bench over here and get a measurement. Just like that here is the course. Now I moved it over here onto the bench so I could film it and as you can see it is quite large. I had to put my camera quite far back over there and it is 6 feet long. That's what it is. I built it on a 6 foot table underneath is a 2 inch styrofoam that I got from Menards and this is the beginning of our rock crawler course for our little 124th scale car. Now the part we are going to be focusing on today is actually right back here from this spot to this spot. Well I'm hoping this goes smoothly but hey you never know so let's do it. So I got the course spun around and I want to go from this here up to this here. Now it's hard to see in the camera but this is actually an angle here that kind of goes back. I can kind of show you so this is straight here and it's kind of angled back like that. So what I have from this spot is roughly 22 inches and that's what we are going to need to start with. So what I'm going to do is get some filament cut maybe that is a little longer. Maybe I'll do like 30 inches a piece for the filament here and then get some planks going and let's see how many planks it's going to take to create a bridge that comes from here all the way down to this spot right here. We are going to get 30 inch pieces of filament and a bunch of planks and let's see how many it will take to actually fill this spot in. Alright so I got my line cut and I got my bridge pieces and now we are going to put these things together. So I think I'm going to start with 10 pieces and we are going to see if 10 will work and if we need more we will put more in if we need less we will take some out. But I think we should do that sped up because you guys don't want to watch me do this all day. So I interrupted the montage with an issue so I'm trying to push the filament in to each one of these right and the problem I'm having is it appears that my next one in line here there's something inside of the hole not allowing that filament to go through. So I'm going to use an allen wrench maybe that'll work otherwise I can get a drill bit but I just wanted to show you the issue I was having is that sometimes when you print these a little piece gets in that hole and the filament wasn't going through. So the allen wrench trick worked I want to pull some more and we're going to keep going. Now that did take me a little bit of time because I had a couple of them that were fighting me on putting the filament through those little holes but it worked out. As you can see here used coax3d mystery roll which just happened to be this orange color here and I printed a ton of these and as you can see in this picture the mystery rolls are like transition rolls that starts with one color and it goes clear and it goes into another color. You can see in some of these that I was further into the roll when I started printing because they're lighter but some of these were nice and dark like the original color. So that is actually orange it's kind of hard to see in here but that's kind of a fun thing from coax3d a sponsor of today's video look for a link in the description below and you'll find a 10% off discount if you want to use them. This stuff is awesome. So what we did was we created the 10 piece bridge here and I'm not sure if we're going to need more or less so that's what we're going to find out now. Let's take a minute and prep the course for the bridge. How it's going to work is I'm going to attach it up here and we're going to spread these planks out so it runs all the way down to here. If I start spreading these planks out and you can hopefully ignore all that cruelly filament because I left quite a bit on the end just in case we need to cut the ends off you know from pushing it through and also I wanted to make sure we had enough I don't want to do this twice. Now I understand that this will be brittle and will break eventually and that's going to happen I understand it's going to happen but for now it's going to be fun and if it breaks I'll have to mount it again with something either more strong or just stronger filament. One thing I noticed on this filament is my bridge planks here we can call them planks tend to slide a little so we might have to hot glue them or something on when I'm done that way they don't go wonky and sliding on us. So I'm going to put five more planks on here to see how that goes and I'm going to do that now. It looks like we're going to make it. I'll spread these out nice so they actually reach all the way down but I don't want it to be too easy as well. I think the next thing we need to do is get it secured up here and then we can plan on how we're going to secure it down here. So something I did not think about with PLA is that hot glue melts it. I just got these in here and I was looking and I realized that it got super thin and stringy I don't know if you can see that. I did not realize that hot glue would melt PLA. So what I need to do is pull some of this back I'm going to have to cut this. I'm going to have to start over I don't think this is going to stay in here. Maybe a PETG would be better and I think that would probably be a better choice and maybe it won't melt I guess I'm going to have to try. Let's try that again. Okay so for now all I did was to slide the ends of the PLA into the foam and I'm going to get some more foam and foam over the top to lock that in. Then on this side I want to bring it down and secure it over here where we're going to be going. So it's going to come from here all the way down to right here. So I'm this far and I think I'm about where I want it. Now it is a good hill here so I need to kind of figure that out. Probably going to pull this back a little bit more so it sits back up in there. But I think either I need to take some planks out or this is going to be a pretty good challenge and I like a challenge. So what I'm going to do is get I brought over a stapler. I'm not sure if that's the right tool for this job but we're going to find out. So this is the stapler here definitely not the right type of stapler you would normally use for something like this but all I want to do is put a staple here and see if it will hold the filament into the side of this little mountain thing here. Now I am going to find some good ways to mount this eventually but obviously my plan originally was hot glue and hot glue didn't work. So we're going to try a little staple here and then maybe I'll do some foam over the top because the foam will really encapsulate that PLA and it'll be awesome that way. I'm going to hit it maybe put it right here. Now that'll hold it in place now the benefit of the staples too is that if I need to pull my filament back because I can already tell it's coming out up here I can do that. So I can pull the filament back and give myself some more up here push the bridge back down this way. Now I'm going to finish this thing up so it's hopefully sturdy enough I'm going to get my crawler and let's see if it works. So this is my Axial SCX24 crawler right here and I'm going to attempt to crawl and go down this bridge. Now I don't believe this bridge is going to hold it but we're going to find out I have a feeling that I'm going to have to do some glue that's not hot glue and get this thing held into place but as you can see it articulates really cool over all these different obstacles and soon as we get on that bridge it starts to sag and we're going to find out if the weight is just too much oh no all the way across well I guess that's the answer to that it did not work the reason it did not work is because these planks slid which I need to find a solution to that and also because the bridge is so steep currently now what I want the bridge to be like is more like this so I want it to be taut and right now it's not so much. So if we try that again looks like I'm backwards here sorry Caleb you can edit this garbage out oh so if we try it again the bridge is a little more straight this time I have a feeling we're going to have the same problem it is not secured good enough what I'm going to have to do is get some glue and put some glue on it because currently it just falls and the truck falls off real quick I want to jump in and talk about things thank you so much thanks for sponsoring this video I really appreciate it things is quickly becoming the biggest 3d model website you can go to there's over five million models now and then the description below you'll find a link to these planks that I printed so you can print a bridge yourself so go check out things with a link in the description below and again thanks thanks for sponsoring this video the bridge is now hanging and it's time to test my scx-24 deadbolt and see if it'll actually go down this bridge I actually ended up using some adhesive that I had I'll show you what kind in a little while here now something to note these planks are not locked in yet I haven't figured out what I want to do there yet but we're gonna see what happens so if we take the car and we drive it over here you can see some pretty cool articulation in the back there oh I might be in trouble the back wheels are already off well that's not good all right here we go so something to note I'm gonna have to do something to lock these planks in because as you can see here this is creating quite a gap now I don't have a problem I think I'll get over it just fine but but that could be an issue later now if I turn this thing back around I'm not sure I'm gonna get up it with those gaps but we're gonna try why not why not nope clearly I need to do some more work on my 3d printed bridge pretty cool though that was a little bit about my 3d printed bridge now this bridge is fully 3d printed as you saw earlier the planks were 3d printed on a prusa mini and I just used white cheap PLA that came with one of the printers as a test for the rope or the connection between the bridge before I forget what I used is this liquid nails extreme heavy duty construction adhesive I had this laying around and I thought I would give it a shot it didn't affect the PLA it didn't eat it which is great and in a day about 24 hours roughly it was dry and I could start driving on it like this it is in a tube something like this it's liquid nails extreme heavy duty this stuff is pretty awesome once this gets brittle and breaks I'm probably gonna have to replace it with something stronger I'll probably go maybe with a PETG or something like that but this was kind of a fun project I haven't done something like this on this channel before this SCX-24 has been just an absolute blast the articulation these things have is amazing I will put some links in the description below if you want to check one out the deadbolt you can get them for around a hundred bucks $110 something like that for the red deadbolt there's also a couple other trucks that you can get there's a whole ton of upgrade parts if you're into RC and I'm telling you these things are a blast you don't have to have a lot of space this is only a six-foot table and I'm not done with this as you can see it's like foam and plaster and PVC and wood and all sorts of stuff this is all gonna be finished off more 3d printed parts to come there's 3d printed parts on the truck I'm probably want to talk about it well thanks for watching the video about my 3d printed bridge like I said everything will be in the description below as far as links and all the good stuff I really appreciate you guys watching and we'll see you on the next one and as always keep printing it is just hanging there I have no idea what it's hanging on oh man you can leave this part in the end of the video that's fine
