This is a little shower shelf that you can mount on the wall without drilling any holes. We got three of the in our shower. I attached the wall mount with a good amount of 3M VHB-Tape. That's all. With that, you can easily remove the shelf for cleaning. Just hang in the shelf itself with a little bit of an angle.
If you want, you can print 1-3 additional hooks for holding dry soap or a razor (see images).
Added a version with thicker walls and three hooks for the wall mount for more stability
