I remixed this from Crosoft's original design so that the ball mount has a thru hole for a 1/4 20 bolt. This remix eliminates the need for an extra piece between the ball and the camera. The original design was for the Insta360 One X camera, but it could be used with any camera that has the standard 1/4 20 mounting hole. I will probably use this with a longer bolt and a set of 2 tightening wheels (one for the mount and one for the camera).
