[MUSIC] [Music] Is this thing on? Hey, Youtube? If you get this message, don’t feel bad about this part of the journeys the end and for the record, it’s 3d printing, a helmet on a small print bed and pieces isn’t as bad as it sounds printers been running for about four days now and I’ll be sanding until at least tomorrow morning, and when I drift off, I’ll think of Youtube. It’s always Youtube [Music] [Music]. Hey, what’s up, Youtube? Welcome back to another episode of three. DIY this week on the show. I’m tackling the prop maker’s rite of passage, the 3d printed helmet specifically iron man’s helmet now. I don’t have one of those big 3d printers that you can get a helmet all out in one go on so. I hope this video inspires you. If you have a smaller printer to try to print something big in multiple pieces and make something awesome out of it, That’s what I’m doing so without further ado since this is a Thingiverse model this week. Let’s skip straight ahead to the 3d printing montage. [MUSIC] all in all the printing process for this build took. I think four or five days. It was a lot to print in a helmets. No small job, but once. I’ve got all the pieces printed out. I’m ready to glue them all together. When reassembling multiple part prints like this, I usually use a combination of CA glue, which is like a gorilla glue or super glue. Crazy glue. You know, those kinds of things and five minute Epoxy, which I usually get at the dollar store. These both have their uses in this sort of situation, So if I have a more flush area where I really don’t want to get any extra glue squeeze-out I’ll use the CA glue, which is perfect for that, and if I’ve got an area with more of a with a bit of a gap where I could use some filler and some structure. The five minute epoxy is perfect once. I have all the pieces glued together. I notice something a little wonky with the mask here since I printed the faceplate in two halves, it seems as though one of those have started a little high. And so there’s a bit of a bit of a gap right down the middle here. I actually have a piece about this exact size. That’s the start of one of these prints that failed, which is just like a beautiful serendipity in my opinion, so I will stick that between the two halves, and I will glue that together and add a bunch of bondo to fill in all the gaps. Let’s talk about Bondo for a second because I’ve been talking about different fillers A lot in my day in my videos lately. I’ve been singing the praises of wood filler a lot over the use of Bondo, but for something like an Iron Man helmet, I definitely recommend using the bondo because of the large size, the size of the gaps and just the general similarities between Iron Man and a car. It’s basically car man and Bondo is car filler putty, so it’s basically tailor-made for this task, So the bondo is gonna get a lot of good use and then once. I’ve done a hell of a lot of sanding. I’m also gonna use some wood filler because that does help smooth out the surface quite some while I was working on the body filler and the sanding the right cheek here, which printed to thin and with some serious gaps pretty much broke, so I filled that whole area with some more bondo, and then I sanded that down, basically carving that down flat with the Dremel until I had reconstructed the shape that was missing. There’s a little part of me, The perfectionist part of me that doesn’t like when this kind of thing happens, but at the same time like knowing that there’s like a piece of this, this model that was built by someone else that. I actually did sculpt myself. I find that really satisfying, so it’s nice to know that that’s there, and it looks pretty solid more so than even the shield. I’m gonna spend a lot of time working on the sanding on this model because I really care about it coming out smooth. I mean, I don’t see the point in making an Iron Man helmet and spending all of this time. If it’s gonna turn out, not looking pristine, you know, okay, after putting in an appropriate amount of man-hours in elbow grease. I finally got the helmet to a smoothness that I’m happy with, which means it’s time to paint. Alright, first. We start with one final layer of sandable primer. I found this really nice, pale gold acrylic paint, which I want to use for the face plate and the other gold sections on the helmet. But it’s not actually airbrush paint and since this is supposed to be a nice, smooth metal car like finish. I don’t want to have any brushstrokes on this surface. So what I’m gonna do is I’m gonna run it through the airbrush by thinning it with some alcohol now to be perfectly honest. I had a lot of trouble getting the ratio right here, and I did end up with some spattering every now and then and just like a lot of work mixing and making sure that I got the ratio right, and then also a bunch of cleaning of my airbrush in between when it gets clogged. I don’t enjoy cleaning a clogged airbrush, but I do love this color and I’m not regretting anything here. It turned out beautiful. Alright, let’s move on to the red of the helmet. I started to paint the red with the airbrush when it occurred to me that the red spray paint that I used for the Hylian. SHIELD project would actually be perfect for this. So when I got that which I really did not regret because trying to use the airbrush to cover something. This big is. Oh, boy, well, it’s not impossible, but it does take a long time, And Andrew doesn’t have the patience look. At how much faster the spray paint goes on. Just, oh, it’s on. Oh, there it is. Well, it’s all all done. That’s just beautiful alright after. I’ve given that considerable time to dry. I’ve got a couple of extra details that I still need to add on, so I’m going to mask out this sort of chin, lower lip section, which is gonna be gold and then. I’ll mix up some more of the gold paint and I’ll spray that down there. And then this version of Iron Man’s helmet has these little silver embellishments right around the cheeks. So I’ll take it some rub and buff God. I love this stuff. It’s amazing it’s it’s like alcohol and wax and metallic pigment all rolled into this little tube. It’s perfect, so I’m gonna actually get that on a paintbrush, which is a little atypical, but I want to be super precise and not have to mask anything off, so I just carefully brush that on until I’ve got a nice metallic look. I’m happy with okay, and with that, we’ve got most of our Iron Man helmet done, but we’re missing one crucial thing eyes. I toyed around with a couple of different methods before I finally decided on how to make the eyes here. I’ll walk you through it. My first idea was to carve the eyes out of a piece of clear acrylic now. I don’t technically have a piece of clear acrylic around, But I do have my old 3d printer. That doesn’t work anymore. I mean nothing. I didn’t break my old printer to get this acrylic. I bought it at the store, so I did a little bit of experimenting, cutting out the shape of the eyes and the acrylic and forming it with a heat gun to get a nice curve going now. I did like the aesthetic of these pieces a lot, especially the second one where I had a bit of a lip to make sure that it fit inside of the eye perfectly, but this piece of acrylic was a little bit thin and so it didn’t have as much pop as I like as much as I ended up liking these sanded, frosted glass effects. Acrylic eye pieces. I decided what I would do. Instead is 3d model, the eyes in blender and print them out in white PE TG, which I know will transmit the light very nicely, so let’s do that cut to a quick montage of me. Modeling the Eyes [Music] [Music] [Music] and here those are my first version fit to exactly, and so the outside edge actually had a little bit of a gap from imperfections in the edges of the print, so I went back in and tweaked the model to extend a little further past the edges of the eyes and printed that again for these final pieces, using a combination of of sandpaper and the dremel tool. I tried to smooth down these eyes as much as I could get them. Ultimately, I’m not the happiest with how these eyes turned out in terms of finish, but I love the shape I was able to get. I am planning on revisiting this model in a later video, and I think in that video I’m gonna replace these eyes, possibly by casting them in resin. Let me know what you think in the comments down below about that, but now. I’ve got the eyes, I will just hot glue these in place so that they stay nice and snug, and then we can move on to weathering right now this. Iron Man helmet looks fresh off the line, and well, that’s fine. I like to think that I snuck into an Avengers battlezone and claimed my own actually used Iron Man helmet, so I’m gonna add some weathering and make this look a little bit more lived-in first. I’m gonna mix up a medium brown kind of paint and dilute that a lot with water slopping that all over the place, especially in the crevices and around the edges to get sort of a shading effect and then damping off all of the excess with the paper towel. I’ll take that same effect all around the helmet, and then once I’m happy with that, I’m gonna mix up a much darker, much thicker, less watered-down paint and more sparingly do the same thing with that one to add another level of dimension to the grime as a final touch. I’m gonna take some rub and buff and just lightly run that along a couple of edges to make it look like chipped, paint has worn off on those corners now for the final detail. I want to put some Leds in the eyes and make this puppy’s glow so here in my old Nintendo switch box full of spare electronics. I’ve got some LED strips. Now these can be cut along these specific points in groups of three, which is actually just exactly the size of my Iron Man eyes, so that’s perfect. These LED strips also come with these special connector strips to make things a lot easier and they have these wires that bridge between them. I’m going to use this as the basis of the wiring. I connect one of my LED sections to either end, and I’m going to cut this right in half, and then what I’m gonna want to do is connect the positive lead through this power Switch that I stole from another device into this set of button cell batteries that are connected in sequence now. I just connect the blue lead for the Leds to the negative. Since I only want these to glow blue and Booya. We’ve got light now. I’m just gonna kind of haphazardly tape. This sketchy wiring set up to the inside of my helmet for now because I do plan on revisiting the internals of this helmet in a future video. Give it a couple of upgrades and with that, my Iron Man Helmet is done [Music] [Music] [Music]! Alright, guys, that’s been in. This has been my 3d printed. Iron Man helmet, sorry. What was that, Dr. Strange? I seriously don’t know how you fit your head into that helmet. Funny, you should mention that how. I supposed to get a head in there. Jack, can you? Could you put your head in there home? No, go ahead. Try to put your head in there because see. Ivan, he can’t put his head in there. That’s that’s that’s not a helmet, it’s a head. Yeah, so funny story. I didn’t actually measure any of this before I printed it. I just kind of took an assumption, and I don’t know why I would since I have an abnormally large head and like all of my snapbacks fit on the last snap So really, I should have known better, but I’m gonna take this as a creative pivot opportunity. And I want you guys to take a lesson from this because I am Iron. Man know what I’m gonna do is I’m gonna take this helmet Head thing head. I’m gonna take this head and I’m gonna put a Raspberry Pi in it and I’m gonna make this into a Google home, so stay tuned for a future video where I turn this guy into a Google home with I’m thinking like the classic idea would be Jarvis, but Friday’s been the thing right lately, so I think I’m gonna have it sound like Friday and I’m gonna control my lights with it and have a smart home powered by Iron Man.
