Another design for adding a second camera, a Blink Mini, to view your prints in progress. This one I mounted to the glass door with double sided tape and the camera slides into the mount perfectly to give a 12 degree downward view of the print bed. It could be modified to use magnets or even suction cups but the tape was a simply enough way to mount it for me. Feel free to modify as needed. I have included the Fusion 360 file.
