Bane Mask from The Dark Night Rises.

I just cut the STL file in half, rotated the two parts, and added supports in Meshmixer to make it easier to 3D print and wear a rigid mask. I plan on connecting the front and back halves with a few bands of elastic and maybe add some padding on the inside. I published all of the files so you can do with them as you please.
The front is printing right now, and has been printing for 15 hours, so I figured I'd go ahead and publish it in case anyone wants to be Bane for Halloween.
Supports are already added to STL files or you can use the bare model and create your own supports.
