I have a pressure fit shower curtain rod, that was tearing up the wall where it was attached. To prevent that damage, and to still have a way to attach the rod for the shower curtain, I made these mounts.
I printed these at a 45* angle, with the rear facing downward and the bottom down. It needed supports from the baseplate, but not anywhere else. I recommend a brim to help hold it in place for printing.
