Model is designed to fit perfectly behind my "Original Prusa Enlosure - Raspberry Pi Mount with 7" Display" model.
For the ball joint, you need:
2x M3 nut
1x M3 16 mm Allen head
1x M3 10 mm Allen head
I am using a Logitech C930, it has a larger field of view as a C920 (90 degree instead 78).
The author marked this model as their own original creation.
