I needed something to safely house a power socket and a switch for my RackPi. This is a simple model that works with DAP Empty 2U Rack Panel (https://www.dv247.com/en_GB/GBP/DAP-2-HE-Rackblende-f-Modulsystem-10-Segmente-MP-1/art-PAH0017160-000) but I think it should also work with a rack https://www.printables.com/pl/model/206043-rackpi-hd-higher-density-2u although I haven't tested it.
I've printed the prototype in HD PLA, but I'm going to print it in ASA, although the prototype works fine. Main part should be printed with supports.
The author marked this model as their own original creation.
