This is a replacement handle for the commonly found quarter turn shut off valve. at least in American bathrooms, unsure of the rest of the worlds plumbing standards.
This was one of my first models after getting my first printer, mostly to learn openscad.
Printed in red PLA I think it looks like a little fire control valve or something, I like it
Note, I made the tolerances way to tight, print at 105% at least for best outcomes.
The author marked this model as their own original creation.
