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.
Print out two each of the bracket and holder files. Squeeze the dremel in between the holders, then slide the brackets onto them. Attach the whole assembly to the CNC as you would the Plastruder module.
