Replaceable Hook

I designed a replaceable wallhook for the towels in the bathroom.
I found out, that all hooks i bought either not stick or break after a few months of use.
so I decided to make a "rack" in which you can put the hook.
so, next time the hook is broken, you just need to print a new one, and simply slide it into the part, that already is fixed on the wall.

I used double sided ducttape to stick it onto the wall.
I sanded the backside of the part, cleaned it with isopropyl and added the tape.
make sure there is no dust and grease on the surface you want to mount it to.

I hope this helps someone ! :)
