This is a small, easy to use mount for the Raspberry Pi Camera module on 2020 extrusions.
The 2020 mount piece can be secured to a 2020 extrusion (as seen in the pictures on my Folger Tech 2020 Prusa i3) using a t-nut and M3 bolt. The camera holder will fit snug over the ball joint, allowing one to adjust the camera's position easily. The camera holder can be printed without supports if your printer can bridge well, if you have the front side (where the camera lens pokes through) flat on the build plate.

(1) 3D printed camera holder piece
