I found ball mount of original model loosening over time and being not stable, so I've replaced it with more stable GoPro-styled mount.
It can be used with plethora of GoPro mount compatible accessories, or - as in my photo example - with Adapter for Articulating Mount & Arm and then with rest of Articulating Raspberry Pi Camera Mount for Prusa MK3 and MK2 ecosystem. I've mounted it on rail with awesome Ikea Lack Articulating Camera Mount
Print with PET-G, recommended 4 perimeters for solid mount
The author remixed this model.
