Pi 4 Under-Shelf Drop Hanger
This bracket hangs a Raspberry Pi 4B/3B+ upright under a shelf or desk. Two slotted holes take #8 wood screws (4.2 mm shank) and give 5 mm of side-to-side adjustment. The board sits on 6 mm standoffs with M2.5 clearance holes on the 58 x 49 mm pattern, and three gussets brace the 94 x 75 mm plate against the 32 mm screw flange. The bracket also has a vent window and two zip-tie slots for the cables, and the USB and Ethernet end stays open.
