104001 Center Diff Cover

I upgraded the center gear to use the LC Racing spur gear and part of the regular WL Toys front/rear Diff. I found the instructions for the upgrade here: 

Once you do this upgrade the gears are exposed and so I created this model to cover the gears. This also prevents wires from getting caught in the gears.

I started with this model https://www.thingiverse.com/thing:5521270 and remixed it to fit the diff and cover all the way to the chassis plate.
