This is a remix of the hook for Schueller kitchen sytems, where a panel system is between the worktop and the cabinets.

The original part by JustPrinting was a perfect fit with it's raw clamp "Rohling". Thanks for sharing this part!

With this remix, I changed the hook, that it can be printed without supports.

The black metal part, is the original part, which tends to fall out of the slot. The printable version is much bigger in the slot and avoids this. The PLA version is strong enough to hang a cloth or a potholder. 

To make it good looking, please change the color in your prints to e.g. black ;)

Print instructions

Print the hook laying flat on it's side. I tested the size in black PLA, which works just fine.

If the hook is needed to hold something heavier than a cloth, maybe PETG would be a better idea.

Modifications welcome

I attached my FreeCad file and the new part of the hook. Feel free to further modify it.
