I remixed Andreas Gohr's “Tiny Raspberry Pi Camera Ribbon Cable Clip” so the 1m ribbon cable of my x-axis mounted pi camera could be attached nicely to the cable of the x-axis stepper for better cable management as shown in the pictures. My design features another circular clip with a diameter of about 5.8mm that fits on the stepper cable of the MK3's x-axis. I'm quite sure it's applicable for rods etc. that share a similar diameter.

Print on the small edges with no support. Brim is required.
