This is a webcam mount that connects to a 2020 extrusion. It slides on and has holes for t-nuts. It has a 3d printed tripod thread that can connect to a webcam or any accessory that fits. Don't overtighten the thread, its strong enough to hold it in place, but isn't crazy strong. I printed it on its side and used supports for the threads, though you might have to use supports for the main body overhangs if your printer isn't extremely tuned.
