This is my take on the Jedi Killer - Grenade Head/Face concept art. The concept was made by Glyn Dillon for Star Wars Episode 7 - The Force Awakens, it was supposed to be the main villain of the movie and it ended up being one of the Knights of Ren.
In this pack there are 3 versions of the helmet, and you'll be able to print the one that you feel you can weather it. 1) Jedi Killer - Clean2) Jedi Killer - Bumpy3) Jedi Killer - Damaged
You'll have to cut the models to make them fit in your printers.
The models are in OBJ format.
