Remixed from this design: https://www.thingiverse.com/thing:2210299

I added two wall hanging holes to this design, printed it with PETG. Mounted it on the wall, works great. Two screws so it doesn't rotate.

Can be removed easily from the wall since it hangs on two screws, personally I added a tiny bit of silicone to glue it to the drywall so it can't get removed easily, but at the same time have the strength of the screws, feels really strong.
