Suction Cup mounted Sink Hangers for Sponges and Scrub-brush

This is a suction cup mounted sponge holder or scrub brush holder. I include a step file of the design if you wish to modify it. You can try to print the suction cup, but I'm not sure it would work very well. It is included so you know what type of suction cup is needed for the design.

With the design as is, you'll need a 3mm x 45 socket head cap screw and 3mm locknut to complete the assembly. Best to use stainless steel so it doesn't rust in your sink.
