Makerbot Filament Guide Bottom (Q34500)

A fix on a student's 3D-ification of part of the MakerBot Plastruder. Here's my fixes: 1: Used the Blender command "remove doubles" to get rid of what looks like about 3000 extra vertices, and re-calculated normals for good measure. (Both steps are always a good idea when working with stuff made from CAD files.) 2: Scaled up by ten-- I think this model may have been done at 1 Blender Unit per centimeter when the scale for skeinforge is 1 Blender Unit per millimeter.
