Dremel Bracket for Cupcake CNC

Turns the MakerBot addative CNC machine into a subtractive CNC machine!

(Well, assuming it works)

This is a fairly hacky-looking first cut, but it slices and I can't see any *severe* mechanical failings. I figure this one can run under the "get out the door quickly, then iterate" model.

I'm including the blender file, which has in it a caliper-captured model of the Dremel tool. It's not the most precise model ever but I think it's accurate enough where it counts to ensure a snug fit.
