I just had a new shower installed, meaning all the hangers and stuff glued to the walls were gone. Looking at that pristine, expen$ive shower wall made me not want to glue more things to it. So I decided to make an s-hook to hang off the grab bars in it. This is the result. Works like a charm, but you may not want to use it. After I designed it, I realized I should have searched first. There's a much better s-hook available. It's much customizable. The only advantage mine has is that it uses a round bar instead of the popular square one, and the other round ones don't seem to be parameterized. If nothing else, they make an interesting study in contrasting techniques.First, consider making one of these instead. Except for being square instead of round, any version of mine can be made on it - and much more. If you want the round version, just customize and print it. You may want a raft to keep the bottom side round.
