Makerbot Filament Guide Bottom

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.
