Deathstroke (Joe Manganiello) in his post-apocalyptic awesome image head from Zack Snyder's Justice League for 3d print,
you will get 2 versions of the head: high (with 850 k polys) and low (with 450 k polys).
All of versions has STL, OBJ, MTL, FBX formats and each of file is signed in accordance with its format and resolution.
Default size is about 5 centimetres (50 millimeters), but you can scale it as you want.
If you have any questions, just text me on instagram (ZBlion_3d)! I will try to help you with your problem.

I think this scene with Deathstroke is one of the best in all of Zack Snyder's 4-hour epic, so it was really nice to make this 3d-model, and I hope you enjoy it as much as I do.
Fueled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne enlists the help of his new-found ally, Diana Prince, to face an even greater enemy.
