About this 3D model
Edit 5/1/2017 : I received a message from from a Thingiverse member they printed this mask at 105% and it fit well. They were an adult male. This is a mask I designed from pictures of Army of Two paintball masks. I would not recommend using this mask for paintball protection. This should fit an adult male but I have not printed it out yet to confirm this. I added decals to the picture renders to give ideas how you could customize this mask.
