centryi4k /centriphone /centripro for yi4k

This is a centriphone case for the yi4k+. Not 100% sure but I think it should also work with the yi4k and the yi4klite. And the camera fits in there with the original underwatercase.

The handle can be mounted for example on a underwater selfiestick for the gopro.
I highly recommend to print it like seen on the picture. There is a lot of force on it!
If your wires are 2 Meters long and you make one rotation per second you get about 7kg on it and easily 20kg wenn you make two rotations per se
