I have been using the Articulating Pi Cam mount with my Prusa MK3S. The joints between the links were coming lose all the time, and the 3D-printed screws were breaking when I was trying to tighten them. I designed my own arm for the mount, which:
- Uses metal M3 fasteners, which can be tightened properly so that they would not come lose,
- Is more than twice lighter than the articulating arm,
- Has a slightly bigger ball for the ball joint, to make that joint a little bit tighter,
- Is compatible with the camera head from the articulating arm, so if you are already using the articulating arm, you can reuse the camera case from it.
