When, after well over 15 years, the handle was so brittle that it broke off, my wife was sad. It was her favorite shower head. So . . . I quickly printed a new one and put it in with superglue. Make sure that there is an air gap to the shower head so that it doesn't jam.

I subsequently enlarged the round recess so that you can open the handle a little wider.
