This is a wearable shaman mask I made from a 3D Scan of a fox skull and some little-big tweaks of my own.
The mask was conceived as a part of my bones shaman costume. The lower jaw is "hinged" with the cranium in a way that when you open your mouth the mask opens its jaw with it creating an amazing and creepy snap sound.
Attached are some pictures of the printing, gluing and painting stages as well as one of the designing process, a couple of my costume and one of my inspiration for this job (http://qarrezel.deviantart.com/art/Genganger-253977442)
The mask also can be used as a Halloween pumpkin!! (as seen in the photos).
Warning: Maybe you should upscale or downscale it in order to fit correctly. We don't have the same head size!
Another trick could be printing only the front part leaving the rear of the head naked (like I did). You can see in the pictures below that I did not use "Mask_up_3_back.stl" in the final assembly.
