Under-Desk Laptop Hanger Bracket
A gusseted C-channel bracket that screws to the underside of a desk and holds a closed laptop horizontally by one edge — print two and slide the laptop in from the front. The channel has a 24 mm clear opening (fits any 14–24 mm closed laptop), a 26 mm deep shelf and a 14 mm top retaining lip with a tapered lead-in; the bracket is 78 x 42 x 32 mm and drops 42 mm below the desk. Four 10 x 5 mm slots in the 52 mm mounting flange take #8 wood screws (4.2 mm shank, 16–20 mm long) and give ±10 mm of lateral adjustment so you can set the spacing to your machine without re-drilling. The whole part is a single prism, so it prints flat on its side face with zero overhangs and the layer lines run across the bending load rather than along it.
