Mazing Man Helmet
For my dad's Dragon-con costume This was one of my first full cradle to grave 3D printed pieces and I learned a lot doing it.
It started in Fusion 360, where I built the 3D model of the helmet. It was basically just a hollow dome with an extruded bottom and some holes punched in it. The real struggle is the bed of my 3D printers are not large enough to print the whole thing at once. So I had to make some strategic cuts in the model to make smaller pieces to print that both maximized space but also mitigated needing additional supports
With all the pieces printed, I connected them with a small amount of super glue and reinforced that with some painters tape. Once it was all together and the glue had dried I took the tape off and then coated the whole thing in a layer of Mod Podge. The seam lines were still very visible so I tried something new and I mixed up a little bit of Durham's water putty. Traditionally that is for woodworking, but it has the incredible benefit that it can be sanded. So after a couple attempts to find the right ratio between the powder and water, I covered the outside in a fairly thick layer of this putty and waited for it to dry. After that I got my electric hand sander out with a low grit and went to work. I then polished it off hand sanding at a higher grit.
On the inside, after Mod Podge, I spray painted the whole thing black, and cut a couple scraps of foam to make a comfortable head shape. Most notably I put a large block in the top so the hole would fall right above the nose. And then put some smaller pieces on the back and around the temples to hold the helmet steady. This gave the appearance that the helmet was sitting on your nose, like in the comics, while actually sparing your nose that weight.
For the eyes, I had to get a little creative. What I did was model a mold of the bulb shape I wanted the eyes to be: an oval half dome. I then made a made a simple mesh model laying flat. I printed both of those out, and using a heat gun to warm the mesh and make it pliable, formed the mesh over the eye shape. I got a little too close on attempt and melted it, you can see in the photos, so it took a couple tries to get it right, but I was very happy with the results.
To complete it I spray painted everything, except the M that was hand painted, and then glued it all together.
