Designed in TinkerCAD.
This is a low-profile, over-the-door, double hook. The part that goes over the door is 2.5mm thick so please ensure clearance. The thickness of the door should be standard for interior doors (at least here in the US) of 38mm (Should work for 1 3/8" - 1 ½")
I would recommend printing in PETG if possible for added strength. I used extra perimeters (4) and higher infill (30% gyroid). I would also recommend using a temperature on the higher side to ensure good layer adhesion. The angled reinforcement is designed so that supports should not be needed.
