In our kitchen the only place close to the sink we can properly hang towels is right underneath on the cabinet. Hanging the towels there loosely however was always a bit messy. We did not want to fully glue anything down, so I put a hook on this useful towel holder to hang our kitchen towels. 

For this print some supports on the hook itself are needed as it has to be turned to add the hook. Not much precision is needed so a layer height of 0.25mm printed perfectly fine, you may even go bigger.

In the picture you can see the towel holders with the small hook, they are perfectly fine for light towels, if you want to use this for heavier towels like in the bathroom, maybe use the bigger hook as they’ll probably break less easily.
