Generic Skull
The curves seem to be gentle enough to print on a Cupcake CNC by MakerBot Industries. Gah...I want a working Cupcake CNC already! Soon. :)

Update: I split this in Skeinforge and there are a few parts on the upper jaw which hang just a bit. This is the only part that may not print properly. The rest of the skull should "in theory" work.

Skeinforge, ReplicatorG, Print!
