4mm bone (2-pieces)

This is a little ear-plug in the shape of a bone, which can be worn in the ear. This particular bone's diameter is a little bit under 4mm. (Requests for different sizes are welcome!) The bone consists of 2 pieces that fit together to make the bone. The extruded bit of one of the pieces is a tiny bit to big to ensure a tight fit, this does however mean it may need some slight sanding.
