Scrubber holder design that will keep your scrubber dry while draining excess water into your sink. Made to fit my sink, so it should work on any standard sink.

The top is printed in PrusaSlicer with a modifier block to remove the all perimeters/layers to zero, set infill to grid at 5%. In my experience, this is the best way to create mesh patterns in 3D prints, creating the model in CAD and printing the stl does not work as printer will not cross perimeters as it does when printing grid infill. The 3mf file of the top part is a project file with the modifier already created. You can open it in Prusaslicer as a project.
