I designed this new version of the Output bell housing in the differential of Tarmo 4 RC car.

I simply noticed that it would be better to use a M2 screw for the power transmission instead of a steel wire. So you can transmite more power and have a more professional look.

You could see on the picture that I lost one of my dog bone, but the outpout bell housing are still in place in the front of the car.

Printed on a Prusa Mk4 in Azure blue Prusament PLA.

PLA seems to work on the differential side of the car due to losses inside it.

I recommend the use of PC Blend : Better heat resistance so less deformation under stress. PC is also better with a lower friction coefficient than PLA.

I tried dog bones in PC and PLA. PC dog bones are still ok after 5 hours of running and 4 runs. PLA dog bones were lasting about 1 hour and one run only (over heating due to friction and finally break under torsion stress).
