Wanted to remove the back and forth play of the driven gear and decided to turn it into a center differential.

Notes:
- I can not recommend PLA for this. It started deforming during torture testing with a drill.
- Every surface that moves and touches another surface should be greased.
- The differential cover should go towards the back of the car.
- The axle shafts differ slightly. The rear one is marked on the end to tell them apart.
- There should be no play between the axle shafts and the diff housing.
- The differential should run smooth without stuttering after turning it a few times by hand.
- This also removes the need to print the gears with supports.
- The attached images explain the assembly.
BOM:
- 1x M3 18mm pin, threaded rod or bolt cut to length

"Happy printing, and God bless, my friend."
