I orginally tried the rack that is described in the Remix file, but found it was fairly flimsy, used a ton of filament and some 64 screws and nuts to assemble. Plus there was no plate that fitted between the side brackets. I only wanted it for two 8 port switches / router and a Raspberry pi, so redesigned it with solid sides and a solid plate to take the hardware. You could double this in height by bolting two together if you wished.

You don't need supports for the screw holes, in fact it prints better without them.

You'll need sixteen M4 x 16mm Flat head hex machine screws and four M3 x 12mm machine screws (with the associated nuts) to assemble it.

Edit: I've had a couple of people want to tip me for this - if you like it and use it, please send a small donation to Link To Hope, a charity I support - https://linktohope.co.uk/donate-form Thanks.
