We have a hardwood countertop and having water pooling under the soap dispensor, sponge, and the tap causes discoloration of the wood. So I set out to solve this annoying problem. As always, I start by looking for someone else who has a similar idea so I'm not reinventing the wheel and then I chopped up that design and tweaked to to the particular dimensions of my sink lip/edge. My sink and counter top is from IKEA.
I added some tiny rubber feet to my print to get it to not slide around.
This design met the approval of my wife, not an easy task to achieve. :P
