Wanted to use this mount system with my Razer Kiyo webcam, so I modified the mount to support a standard camera screw. Someone else made one with a short track, but my version is a bit thinner (4mm) so it works better with the camera screws I have (5mm threaded, 5mm unthreaded).
The author remixed this model.
Modified ball mount to have a 4mm base & standard size camera screw hole.
