I needed a simple hook that can be used on the inside of a door. To easily modify this, I designed a customizable version with OpenSCAD.

Changelog:

+ v1 : very simple hook, with no supports; might distort + v2 : v1 with supports, no distorts, can easily carry 1kg + v2.1: v2 with a rounded hook (to reduce stress at the clothes), a little ramp (easier fitting beneath rubber seal) and rotated (to start printing)
