Prints without support. Either as the full thing or as parts to be easily painted and to put in the eyes you like as well as being able to rotate them. You could even put some strings on the eyes to control them. Or just get rid of all the eyes, put a light inside and use it as a comforting night light for your kids.
When you put the mask off be prepared for a horrifying discovery!
