I was building a small Raspberry Pi Cluster, and printed the "Raspberry Pi Rack case or rack cluster" by yooodaha. Then I saw hubschrauber's stand for the Netgear GS108. I liked the design, but I already had a TP-Link switch in a drawer, so I made a similar design in OpenSCAD.
I used a M5 threaded rod in the Raspberry Pi Rack, going through all four pillars, and on the top and bottom I have a regular M5 nut. My cut of the M5 had a few sharp edges, so I printed some nut caps, which then fits into the TP-Link stand.
Edit: Added a version, with longer legs.
Regular version goes from top of the switch to the bottom of the metal case. "Higher_feet"-version goes a bit further, and includes the length of the rubber feet on the switch.
