wearable Bobby mask

a roughly head sized and wearable mask modeled after the Bobbies mask from the game "We Happy Few"

Note that the mask should be scaled slightly up or down, to get a comfortable fit.
Prints without support, but will need a brim or raft, since the bottom contact area is rather small.
