Quick Klein Bottle - OBSOLETE

EDIT: This is superceded by this http://www.thingiverse.com/thing:449

Wanted to see how badly some of the tool chain would choke on a Klein bottle, so I made one the simplest one I could. Had to do it by hand in Blender, since this is kryptonite for TopMod.

I think I got all the normals oriented properly... at least it renders ok.
