This is an X Axis Rail mount for "CR10, Ender Logitech c920, c270, c310, c910 20/20 camera mount system" by FedorSosnin - https://www.thingiverse.com/thing:3147899
Created by merging FedorSosnin's 2020 mounting system in the link above, with the rail cover made by NeoExacun. It's just friction fit, no hardware.
Only the X Axis mount provided, get the rest of the camera mounting system from the link above.
Front edges have been bevelled to give probes like the BLTouch some wiggle room when homing as mine was getting pinched a little by NeoExacun's design.
You might get some vibration from the printer on the camera. I found just tightening up the nuts stopped it enough that it wasn't noticeable on the live feed, but you may want to set a slight delay on timelapses for the vibration to stop before taking the picture.
I printed without support at 150mm/s (Klipper) without issue but if your printer isn't quite so fast and well-tuned I suggest using support.
3 walls, 3 tops/bottoms. 0.2 layers.
