I started from the design https://www.printables.com/model/108115-bouton-de-robinet-darret-wc made by Paterne and I added the stops to the bottom part so that the tap closes and opens on 1/4 turn (Blue arrows)


Printing instructions
Printed in Prusament PLA Galaxy Grey with PrusaSlicer standard parameters using
Support are needed for the bottom part. I used Paint on Support feature to define where supports are needed


On top of .stl and .3mf files, I uploaded Fusion 360 .f3d file so you can modify the design and adapt it to your needs
As usual, feedback and comments (and for sure "likes") will be always welcome. Feel free to post nice pictures of your makes
