Ender 3 Camera mount with lockable ball joints

I drew this mount from scratch (except for the camera case), because I got tired of re-aligning [this](https://www.thingiverse.com/thing:3516462) camera mount after each time I touched it.

I has two lockable ball joints, so you can align it as you like and it will stay in that position.

The nut can slide over the ball. Slide the fitting over the ball to lock the nut in place and you can then tighten it (see assembly drawing).

I features printed threads, which required a very precise print, so be sure to print the nuts and fittings with their threads up (not touching your build plate) and one by one (to avoid small distortions due to stringing).

All parts can be printed without supports (al least on my printer).

An M5 screw is required if you want to tighten the mount to the Ender casing. The M5 thread will already be printed.
