I wanted to mount the camera in the corner of the printer, but after some trail and error I had to conclude there was no room. I still included the design files, for if someone finds a way.

Finally hooking the mount around the front panel, around the top seemed best.

I improved upon the following existing ball joint design: https://www.youmagine.com/designs/parametric-ball-joint

I found that the camera needed to be enclosed, for proper image quality. Without a case it seemed like you saw the inside of the lens mount. So made a camera case holder that encloses the camera module (UM_camera_case).

The design is created parametrically using OpenSCAD.

Update: I added some space around the joint to keep it flexible.
Update2: I tweaked the retraction settings to make the support break off more easily.
