Soap saver

thingiverse

A simple solution for avoiding over-enthusiastic soap dispensing: attach this tiny accessory and forget about pumping too much liquid into your hands. This add-on fits standard soap dispensers with a diameter of roughly 6mm. To adjust the dispensed volume, simply stretch it out in the z-direction using your slicer. In my case, a height of around 9mm yields a full pump length of 12mm, leaving 3mm for extra soap and still providing ample cleaning power to wash your hands.
