I was looking for a mount for my Logitech C920 on my CR-10 Mini. I couldn't find anything that worked with my printer placement. Most stuck out too far, or vibrated too bad during the print. This is a pretty generic thing, but it worked well for me so I thought I'd share.

Mount to frame - M5-.80 X 10 I used the extra nuts that came with the printer. The bolt was a bit too long so I picked these up at Lowes
Mount to camera 1/4-20 X 1/2
