Summary

Remixed Differential from Thing-O-Fun.  I added the Yoke to make it more realistic.  The original files had a lot of play and were not all consistent sizes which are now consistent.  I also redesigned the spider gears to accept screws from the outside to allow 4 spider gears to be installed.

Addition:
I added a stand with a motor from here http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2128219_-1.  Use the 2 spur gears to drive the entire assembly.  Motor can be wired to a USB port.
