Mass Effect N7 Breather Helmet

Edit 5/15/2017 : After some measuring, it looks like 80-85% is closer to adult size head. Thank you Jace!! I used his model as a reference for mine. I was so excited about the new Mass effect game coming in March, I decided to make my favorite helmet from the game...The N7 Breather Helmet. To assemble the helmet: Parts are numbered. Part one is the Front Top Left. The move left to right - Top to Bottom - Front to Back. I would like to thank jfleming44 for providing the printed pictures.  His model turned out great. https://pinshape.com//3d-printed-object/6489-mass-effect-n7-breather-helmet#comment-1766
