Ergonomic water saver ring diameter 24 mm

With a wet hand, the water saver I used was sometimes difficult for me and my girlfriend to switch between the full stream-shower modes.With the ring in place, switching is much easier.The ring is intended for a diameter of 24 mm.A little thing that makes everyday life easier, at least for us.Printed from PLA (possibly PETG,ASA...) with a 0.4 mm nozzle, filling 20% and with a brim
