Soap dish with drains for dripping any excess water over the sink instead of collecting it in the bottom and cultivating life forms. Also has ribs on the bottom which makes it work nicely even without that fake grass "soap pillow" in the picture.

The bottom and the drain pipes are slightly tilted to help drain any water, but this will likely create a stepped surface due to 3d printing layers, which should be lightly sanded or filed smooth for best results.
