Linear Bearing Y Stage for Cupcake

Still upgrading my Cupcake! This is a compact lightweight Y stage for the Makerbot Cupcake that uses SW4G linear bearings.

note 11/1/12: I added an 8mm version as well since Apparently some Cupcake models use 8mm rods. This should fit an LM8 linear bearing. This is untested - I am assuming the rod spacing is the same as my model.

11/3/12 I added two more experimental versions modified to fit the Lowrider - 1/4" and 8mm versions. Also original Rhino 3d files
