Cupcake Bearing Bracket (bb)

Just a replacement for the stock 'bb' part on top of the bot. One of our used bots had the stock ones glued on, and we needed replacements.

Only after I made this did I realize I could probably get one from here: http://www.thingiverse.com/thing:3285

This one is an OpenSCAD extrusion of the stock .dxf cutfile from MakerBot.
