Thank you original uploader, this one is awesome!

I used SUNLU Matte Bone White filament, 0.12mm layer height and tree supports.

Take your time trimming supports around the teeth. May need to be reoriented to avoid supports going too deep through the skull, although I didn't have much of a problem.

I used a dremmel to sand around the top of the skull, nose and lower jaw.
