Tripod adapter for Kinect

This is a simple tripod adapter for the Kinect that requires only one non-printed part, a 1/4" x 20tpi jam nut.

I'm marking this as a work-in-progress because some skeinforge configs don't like the STL file. Mine complains but my Makerbot Cupcake prints the right thing, so it's probably not going to stall anyone else's printer.
