This is a G.I. Joe Cobra B.A.T (Battle Android Trooper) 1980s Helmet I was commissioned to make. This is outside my norm but I had a blast making it. Brought me back to my childhood, Playing on the floor with my G.I. Joes. Im glad I could make this for you.
1.- For sizing I recomened using my FREE Heads for Sizing on Thingiverse
