OpenSCAD shower shelf (pole attachment)

thingiverse

Don't assume it'll conform to your setup, instead tailor it using Openscad.\r\n\r\nThe printed piece with 20% infill is more than sufficient. In fact, the entire thing would have functioned better if I eliminated the bottom part of the clamp. Additionally, consider adding an extra 1mm clearance - it won't drop anyway, and you can avoid almost ruining your shower like I did.
