Network Switch Jack-Screw Wall Cup Pair
A U-cup wall bracket that grips one end of a desktop network switch or router. Print two: mount one under the device and one upside-down above it. The 36 mm channel takes gear 8–34 mm thick, and an M4 screw in an M4 heat-set insert (5.5 mm bore) in the front lip clamps the case against the back. Each cup fixes to the wall with two #8 or #10 screws through 5.5 mm holes below the floor, so the screw heads stay clear of the device and nothing depends on the case's own (usually missing) keyholes.
