Darth Nihilus mask for 3D printing. There is a few different versions of this mask but kept this one pretty simple and went with the general look. The colouring shown here is for reference, I liked the bone look to this mask, rather than the white...but that's up to you.
I have included the .stl and .obj files as well as the original blend file. Let me know if you need any help sizing this one.
Happy Printing.
