This is a remixed model where I just added a ball joint in Shapr3D. I should have tested the ball joint fit into the socket properly before printing the whole part; however, on this one, it was too loose. Adding a bit of electrical tape to the ball allowed the camera to mount and stay in orientation. All other settings remained the same.
The author remixed this model.
I added a ball joint to the end of the mounting face to allow me to attach a webcam, which had the matching socket.
