Each shower rod end has one recessed screw hole in the center. There is usually a stud near the edge of a fiberglass one piece shower unit. At 100% the .stl files are O.D. 35.5mm and the I.D. is 25.5mm. I'll include the .f3d for editing. no more shower rod falling down. My kids abused this for a couple years.. no problems yet. I printed in PLA, silver.. can't even see any delamination.
