Modular 10" 19" Rack Mount for 5 Port Switches

Summary

I wanted a space efficient mounting system for the standard housing for 5 Port switches, which is used for a lot of switches by Netgear, Mercusys, TP-Link including Omada even the Omada Controllers OC200 and OC220 sitting in this form factor. So I figured, that it should be possible to fit 4 of them in 1U 19" Rack unit.
I designed it modular and fits in 19" or 10" racks.
For 19": Print 2x the "Rand" (edge part) and 2x the "Mitte" (middle part)
For 10": Just print 2x the "Rand" (edge part)
The parts are screwed together with M3 x 10mm countersunk screws and M3 nuts ( https://www.amazon.de/dp/B0FVXKY2CD ) in the recess in the next part module. If the your printers tolerance isn't the best, then just heat up the nut with a lighter or s.th. and it melts easily into the recess, where it meant to be.
For full assembly just rotate the 2nd "Rand" (edge part) 180° on the other end and you are good to go.
Have fun.
