Biqu B1 Ball Joint Camera Mount

I am using this holder together with gopro ball adapter. Gopro system is used to connect raspberry pi zero system (octoprint) equipped with camera. Compatible ball joints with threads or gopro mount: https://www.printables.com/model/370429-generic-lockable-ball-joint https://www.printables.com/model/382577-gopro-mount-for-lockable-ball-joint Raspberry pi zero case with gopro joint: https://www.thingiverse.com/thing:1709013 I recommend to use version with 18mm ball joint. My 12mm version works, but ball jont cannot be tigtly locked. It is possible to move joint even if the screw is tightened. Holder can ve secured to the printer body by double-sided tape if needed.
