Trollface Mug

You only get to drink 1/4 cup of coffee from this trick cup. Once the beverage level goes down, a troll face slowly peeks up, showing you you'll never get the full cup's worth.

I have yet to do a print of this, so no guarantees the face will appear as crisp as my 3D renders.

Shapeways said the solid bottom of the cup was not allowed any more, so I am updating the model to become hollow on bottom. Sorry for any inconvenience. I am also making sure it works with a test print.
