I just finished this, so I figured I would post it up. The bottom edge of the "chin" probably needs to be wider, but since this is the only y-wing helmet pep in existence, I don't think anyone will complain too much :P The depth of the inset areas is exaggerated to allow for resin and bondo, so don't freak out about them being so deep. Also, the top of the head is a bit square-ish, but is only noticeable at a certain angle. I have attempted making this thing several times and they all looked like a Picasso painting of Jabba the Hutt. I am very pleased with how this one turned out. Thanks to Ywingfighter for the references. I may model the visor as a vac-form buck, so you guys with vac-forming equipment can make your own visors. Speaking of which, if there is a visor that is hard to find or make, send me a pm and I will try to model a pepakura buck for vac-forming.
This is a .pdf of a Pepakura development, so scaling up may be difficult, but you can always make it smaller if needed. I used a model of a head inside the helmet to visualize the scale compared to screen references, then I measured my head. It should be about right, but my math may be off for the metric conversion. If it is totally off, I will release the .pdo individually by email and pm.
Anyway, on to the file.
