I designed this for sponges that are 102x62x21 mm, but these measurements can be altered easily using the .scad file if your sponges are a different size.
The .scad can also fit different numbers of columns and different heights. Cutouts will populate automatically.
Pre-prepared stls will print 5 or 10 sponge heights, in one column or two.
The author marked this model as their own original creation.
