Long and short of it. My bathtub’s spring stopper has deteriorated. Building manager solution was to use a rubber stopper. I looked for a replacement part, couldn’t find one outside of an outright replacement. So I modeled and printed this one in TPU.
It works!
What was the verdict then?
It works but has a leak somewhere. Without seeing where that leak is, clear tube or seeing the underside, I’m just guessing but it’s so slow it doesn’t matter.
Wider didn’t help as predicted in this thread.
Good for a stopgap, not good if you need to hold water for over 8 hours
