I have a glass shower door that had broken spacers allowing the handle to rattle into the glass, I was able to disassemble it and use calipers to duplicate the measurements. the piece came out perfectly. I have printed this in polycarbonate, petg and PPA-CF and all of them seem to work. I installed the ones in PPA-CF and kept the polycarbonate ones as backup. Hope this helps someone in the same situation.
