Welcome to witho engineering today. I’m going to show you how I built this A 3d printed r2d2 Dome, So I found the print files for this r2d2 when I was perusing the finger verse, I kind of stumbled upon them and always wanted to build an r2d2 but it seemed really complicated, 3d printing seemed to strike a nice balance of having a high quality r2d2 as well as easy to build and low cost. This specific design was put together by a gentleman named Michael bad way. Michael has assembled a complete set of print files as well as a set of instructions to go along with them. There’s a onedrive account that Michael hosts that has all the print files shown on it and I’ll post a link to that in the description down below. I printed all the parts for this dome on Mike. Reality CR 10 using the Amazon PO8 filament printing. The dome took a very long time. Each of the six like main domed pieces took between 15 and 16 hours in number. Six of my r2d2 Dome is done. 3d painting, lets. Take a look at it so there we go all six. Those six pieces of the r2d2 dome are all successfully pertinent. Looks like they will fit together pretty nicely. I just need to print the two pieces that go on the top to check that this is turning out cooler than I thought it would be. This is pretty awesome. We got the dome printed lower ring printed upper ring printed. So this is all six pieces of the dome. They’re numbered one through six, get assembled. Numerically kept going counterclockwise, so one two, three, four, five and six. What I’m gonna do now is go ahead and sand all these pieces down a little bit and make sure to clean up the edges so that I can then go ahead and glue all six of these. Don’t pieces together and get a nice flush joint under you, get to start. [MUSIC] I’ve got all those pieces sanded down and now I’m gonna glue them all together. I’ll be using this flat flooring towel To ensure all the pieces are flush when they go together and I’m using just regular super glue to glue it with all the pieces together. I ended up using these medium binder clips like this to hold the dome together while I glued it. Let me show you so just three binder clips on each joint there next up is the upper pipe piece and it printed in two parts. That’ll glue together and then. I’ll then glued that on to the top of the dome, so I finished going together. The entire dome, including the PI piece on the top. The next step is to sand it all down. Apply some wood filler in the seams and then sand some more until it’s all nice and smooth and ready for paint [Applause] [Music] [Music] [Music]. I’ve got that all sanded down. I started off with 100 grit, sandpaper to sand it down, and then I went on to 220 grit sandpaper. The next thing I’m gonna do is take some of this filler primer and spray down the entire dome, so I can sear all of the imperfections are in it, so I can go back through with the wood filler, fill in those imperfections and sand it down some more. This primer will really show off, though areas where I’ve got little divots in the print or where the joints in between the pieces haven’t come together very smoothly [Music] so after the first coat of flow primer. This is looking pretty good. I’m gonna go back through with a couple more passes, so I can get a really nice finish. There’s still some noticeable 3d print lines and the joints in between pieces are still visible. I’ll use more of the wood filler to I kind of flawed, any larger imperfections. So I’ve got the dome all sanded down, And now I’m gonna go apply the silver topcoat to it. Oh, uh, something. I forgot to mention there’s. These little tabs here that need to be removed. They’re supposed to come off with pliers, but I’ve been using these little cutters to remove them. They’re just little support tabs for the 3d print for areas where there was a large span, something to go ahead and remove all those. So after three coats of paint, the silver part of the dome is complete now. I need to go ahead and sand down all the panels that get inserted into the dome. [APPLAUSE] So now I’ve got all those pieces, sanded down that get attached to the dome, and now I’m gonna go through and sort them out by the pieces that need to be painted silver and the pieces that needs to be painted or you know, Purplish blue sonic blue in this case, so all of these will get the painted sonic blue and all of these will get peanut sonic blue. All right, number one code number two, all right now next. I need to paint all these pieces. All these pieces are getting painted silver. I’m using a rust-oleum metallic paint for my silver and like that. They’re all silver. All right, I’m gonna attach all the pieces to the dome now. I’ve decided to use hot glue because I don’t love these to be permanent. There’s some cool modifications I can make in the future to attach servos onto the dome so that these panel pieces actually fold out and the upper pie piano pieces fold out as well. I’m using servos, which is a modification. I might want to make also. The finish isn’t super nice, and I think I might go through Waiter and Refinish the you’ll refinish the entire dome and all these Panel Pieces [Music] [Music] [Music]. So now I’m gonna work on the way, see Susan that the dome rotates around. They’re kind of, like four main parts to this lazy Susan. There’s the lazy Susan itself which I bought off of Amazon. This is a four hundred and fifty millimeter lazy. Susan, I’ll be voting for the one I purchased down in the description down below. Then there are several pieces that go together to form the main gear. There’s this smaller gear, which will have a motor attached to it and little spin kind of the outer gear, and then there’s an upper ring, which is made up of six separate parts and the lower ring, which also has six separate pieces to it. So what I need to do is I need to sand down each of the separate pieces, and then a pop of glue them all together. And then I’ll assemble those kind of three main components after that [Music] [Music] okay, now let’s screw together the upper ring, the upper ring is made up of six separate pieces, and if you have the flat side facing up and get assembled in numerical order going clockwise, so goes one. Two, three, four, five, six seven. I want to glue this with the flat side on a flat surface, so Ill. Flip that around, which would then make it one two, three, four, five six and seven [Music]. So the upper ring is now all glued together. I’ll let that dry, and then I will go and glue together. The lower ring, all right, so I have the upper ring Easy camera. We’re trying to film here. Strap you down, all right. The upper ring is all glued together so now we’re going to do the lower ring so where the upper ring was numbered, one through seven going clockwise. The lower ring is numbered, one through seven going counterclockwise. That’s what the flat face is facing on. I will glue this one again with the flat face down, so I get a nice, flat surface. That’s all dry, lets. Uh, sand these down to get some nice, smooth edges. [MUSIC] So I apparently didn’t film this next part, but the gist of it is, I painted the upper ring in Sonic blow and the lower ring in the silver so to attach these rings to the dome. What, I’m doing the orientation that I’ve gone with is I have the lower ring with the flat side facing up, and then I have the upper ring with the flat side facing down and then the dome. I’m then using 35 millimeter m4 machine screws and running those up through the outside set of holes. It took me a little while to figure out a configuration. I was working for this, so I’ve already found. I’ve already started one hole and I’ll show you how I do. The other 504 millimeter nut or m4 nut, So the instructions for this part of the bill Didn’t make a whole lot of sense to me, but I believe I have it correct. So I added four machine screws going through the lower ring through the upper ring and into the dome. So there’s a nut right here, The machine screw coming through, and then there’s a bolt holding it all together, and then there’s four machine screws evenly spaced around the dome. So here is my completed r2d2 Dome. It’s completed in the sense that I still need to add the lazy Susan to it, but that’ll be in the next video as well as the electronics that go into the dome, including the TCS lights and the hollow projector lights. I’m really happy with how this dome has turned out. This has been a great 3d printing project that I would encourage anyone with a 3d printer to take on r2d2 is such an iconic character in the Star Wars franchise. So it’s cool to build, You know, an r2d2 myself. So this is just the first part of what should be at five or six part series, going into the complete build of a 3d printed r2d2 you can subscribe to my channel down below fight of all the future r2d2 video updates, and you might consider checking out some of my other 3d printed Star Wars helmets that I’ve built. Take it easy!
