When turned too stong, this original part of your bathtub can break - mine was made from rather thin plastic. Print a spare part. To find out whether this fits to your bathtub: - my bathtub is an European model. - in the middle of the pipe there is an octagon-shape with 8.4mm diameter that fits to a octagon axis of 8mm. - compare my construction with your original handle

The part is printed without brill or supports, with 25% infill, I made it in PLA. It fits to the original tub without gluing it, just snaps on. The opening in the outer circle lets water overflow if necessary, so it has to point to the bottom of the tub.

You get a file with the ingravement "there is no place like home" and one file without writing.
