This is a part for an Open source 3D printed robot called InMoov that I'm building. You can find it here: http://www.inmoov.fr. The servos are hacked for continous rotation and the potentiometer extracted to be able to measuse movement, But the small potentiometers from the servos break easily. So the parts here can be used to replace the potentiometer with a larger one, with a 6mm axle. The video shows how to put things together.
Update 20161105. Uploaded new version of 6mmPotholder. The previous version did not have the correct hold. It is intended for the old version of the shoulder. Added two versions that fit the new shoulder design. v1 is without a cable guide, v2 with a cable guide.
This video shows how to mount the potentiometer to the shoulder
