Raspberry Pi Camera Mount with Ball Joint

This is a Raspberry Pi camera mount for an IKEA LACK enclosure. The mount plate nicely attaches to a LACK leg with a screw.
I tried 3dkarma's design but didn't hold very well. So I improved the ball joint design for better grip. Instead of two arms grabbing the ball I used a full form socket. The socket is only 0.2mm larger than the ball. Also the socket covers slightly more than half the ball to increase fit and friction.
For your printer you might need to adjust the ball radius (prints faster than camera holder with socket) for a good fit.
The ribbon cable clip was reused from WaveSupportAparatus.
Prints without support.

*Update*
v5 fixes the boom arm to a 90deg angle from the wall mount. I found that my boom arm would swing back ad forth due to lack of friction.
