Inspired by the "impossible tilt mechanism" https://www.thingiverse.com/thing:1035497/files I created my own tilt mechanism for a brushless motor 2212
The servo mount and the bearing mount are put on a 12 mm carbon fibre tube.
A small ball bearing (3mm inside, 6mm external diameter) fits into the bearing holder. A short 3 mm axis is pressed into the motor pod.
The servo is a Robbe FS 166 digital type with metal gear and ball bearing. Dimensions WxHxD 23x9x24mm
Please note that my photos show the first prototype. After taking the photos and before uploading the stl-files I changed some small details. I planned to align both the servo mount and the bearing mount with two 3 mm carbon fibre rods. But that wasn't necessary in the end. And I cut off the upper retaining bracket of the servo. You will also have to fit the lower bracket to the tube. One can fasten the servo with a cable tie. Until now I did'nt. At last there is a small cable channel inside the servo mount.
