About this model

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 Use the 2 spur gears to drive the entire assembly. Motor can be wired to a USB port.
