Summary

I accidentally broke my gimbal in a crash. The motor holding the camera can rotate freely. There is a cable inside that can only handle a few turns. This thing can prevent that from happening, saving the gimbal.

You need to print 2 of these.

I used thin but very strong double sided tape the stick both parts to the motor. You can choose where to block rotation by carefully choosing where to stick them.

It will influence the balance a bit, but I found no ill effect in the perfomance.
