Scarab Box (Tuned for Cupcake)

I made a few changes to the original that make it easier to print on a MakerBot Cupcake. I printed it raftless for smoother, flatter surfaces.

Changes: (1) slightly shrunk the gear teeth, so they mesh well without sanding; (2) adjusted the dimensions of tabs and holes for better assembly fit; (3) removed some non-manifold geometry from the inside.
