This door hook is designed for quick and hassle-free installation. It is a simple yet effective solution for hanging clothes at the top of your doors. You can use it with or without a coat hanger. The hook shape is intended to avoid leaving a "neck nipple" when hanging your cloth directly to the hook.

It was designed for 40mm door thickness. You may scale it to suit your need.

Printing instructions:
Material: I used PBT as their hook part has a steep overhang at the beginning. Together with extremely well PEI bed adhesion, PBT can handle it with ease. I tried Polymaker PETG but the result was not bad but not as good as PBT. You may try PLA as well.

Search PBT filament in Aliexpress for a try. I didn't buy from Aliexpress but the cheapest one should be the same as mine.
