Iron Man Mark 37
This is intended to be 3d printed and worn as a costume. I am unsure as to if it actually works as such since I am yet to try it myself, but I figured I'll put it out there and maybe someone smarter than I could do something with it. It was sized to fit a 6 foot 180lbs man, the thickness is 2.5 mm, and there is no helmet since I saw there was already one on here.
