Looking for a clean place to put sponges or soap to dry, I had a hard time finding something that was simple and clean.

This is a refinement of my original design and builds on learnings from the first version:

1. make it easy to rinse clean
2. add space for it to dry underneath
3. add a lip to keep it at the edge of the sink

Recommend printing with a 0.8mm nozzle, 0.4mm layer height, and 1.999mm extrusion width. This produces a strong part when printed in “vase mode”. See the included .3mf file for a good configuration. It can also be printed with a standard 0.4mm nozzle and 0.2 or 0.3mm layer height, but I have not tried it.
