This is a remix (see linked original). I just slightly adjusted for my needs and thought I'd submit the remix if others wanted also.

I made the cable holder singular, as I'm using a Hat and the ethernet cable holder/mount is not needed. It is slightly shorter and is raised with a divit for the RPi psu cable to be seated and used with a tie wrap/cable tie. I chamfered the screw hole and put a slight fillet on the edge. Everything else is the same design.

The origninal I printed was in PETG but this one is in PLA+. Both came out great.
