I really liked the idea of Randyre's C270 mount that clips onto the end of the X-Axis belt tensioner. However, I wanted it closer to the gantry to be more out of the way, and wanted to be able to quickly remove the camera if I want to reposition it.
I borrowed the mounting hole, which is a perfect fit over the belt tensioner. Everything else is new from the ground up.
The clip slides over the webcam's hinge and locks in securely, while still being easy to remove. The webcam mounts upside down, so that the body and USB cable point toward the back of the printer. The camera angles downward subtly to see more of the bed, as shown in the photo from my webcam.
I've lined it up with the printer's hot end as low as I could go without running into the touchscreen. Your printer might be different from mine based on whatever mods you've made. If you need a height adjustment, let me know and I'll be happy to do that for you.
This has been tested with the CR6-SE and Ender 2 Pro. If it works for you with a different printer, let me know and I'll add it to the list.
