An over-door hook with no screws and no adhesive: it drapes over the top of a door, cabinet face, or fence board and grips by shape. The one measurement that matters is door thickness — measure with calipers or a ruler and the hook sits flush instead of rattling.
Hook reach is how far the hook sticks out (24mm suits coats and bags; go wider for helmets), and the lip keeps things from sliding off. Add the second hook for a two-tier hanger, and the 45° brace if it'll carry real weight — the brace triangulates the hook against the door face.
Print tip: lay it on its side in the slicer so the layer lines run along the load path — a hook printed upright snaps at the bend. PETG with 4 perimeters carries winter coats.
