As my wife always complained about the kitchen sponge cloth falling off the water tap, I had to make a new invention to keep it from falling. As the sponges always shrink when they get dry, they easily come off the tap and this ring will (probably) hold them back. It's in use now for almost a week and it seems to be working.

UPDATE 2019-07-05:
I put a rubber band between the water tap and the tool to prevent it from getting too hot and falling of (because of the PLA melting temperature), maybe better to print it with PETG or TPU - as I avoid printing ABS...

UPDATE 2019-07-06:
Version 1.1 is designed to be printed with TPU - and to be supported by a rubber band for better footing. Print settings for my ENOTEPAD TPU (black) are 230°C printing temp, 30mm/sec max, 0.12 layer hight and support touching buildplate, infill 60%
