Gridfinity (3x1) - Sponge Rack + Basin

This simple module is compatible with Gridfinity systems. Washing your baseplate regularly is important. However, I did not want to leave my 3D printing sponge next to my other sponges for regular dishes. I also wanted it to be next to all my other 3D printing supplies and tools that are already built within a Gridfinity ecosystem. It comprises of two parts: (1) a sponge rack, with holes for airflow, and (2) a basin if you don't have the habit of squeezing your sponge dry, while serving as the in-between for compatibility with Gridfinity systems.
