This is a camera mount for the Creality Nebula camera. It is designed to be mounted on the left side on the upright. It simply snaps on to the upright with tabs holding it in place by gripping in the roller channels. I downloaded and printed some. Mounting on the left side made more sense to me because I have a Sonic Pad installed. It was designed using Autodesk Fusion 360. Any comments, suggestions, or requests would be appreciated.
