I really enjoyed having a camera that stayed level like I had on my other printers. I couldn't find one I liked for the MINI+, so I made one

The C270 will likely need a focus ring to accommodate for how close the camera is, but together they keep the footprint within a centimeter of factory spec

Hardware is just one M3x20 bolt and nut (which sets against a ledge so you wont need two wrenches to tighten)

The camera bolts in from the bottom and is held vertically centered on the nozzle tip.
The cuff slips over the end of the X Axis and two little features index in the holes on the top and bottom plus, a channel for the cable to guide it vertically
I secure the cable to the highest point of the bowden tube with enough slack to reach both sides and again a few more times with other cables after that to keep everything neat on the way to the Pi
