I just wanted to know if I could scale it, say like this: my chest is X mm wide, could I change the scale in pep designer for the foam torso to X mm wide and it actually be that number in reality? what I'm getting at is that a friend of mine built a MKVI helm, and it was wayyyyy to small, and I want to get this chestpiece right the first time, and not waste a whole lot of foam since my budget is at $0. lol
