This is a rasp cam heatbed mount with very tight tolerances for Prusa printers. As you know if you have built an ikea lack enclosure or similar there is not much space for a camera. I took an existing model of a pi cam mount and edited it to my needs. Hopefully it will work in your situation too. One model has a slot for the ribbon cable the other does not. Will need a longer screw for the heatbed in the corner, I used one out of my spare parts bag.
(UNTESTED: ADDED SOME BALL JOINT MODS TO GET BIRDS EYE AND CLOSE UP VIEWS)
