Inspired by the 1997 film Princess Mononoke, this is a mini version of the mask worn by the character San.
If anyone is interested in a full size, wearable version, please let me know and I'll put it on my to-do list.
EDIT: Fully wearable version is all finished here
Printed on a Rep-Rap i2
0.3 layer height
2 layer wall thickness
just glue the two parts together and paint!
