My mother requested a dish to hold a plastic fingernail brush that she had.
This particular design includes my modules for making cubes with rounded edges.
Then I decided that I should customize it a bit, so I experimented with 3dplot.scad, and then also added in some personalized text on each side.
I put my mom's name on one side and my name on the other.

I might have slightly modified the 3dplot.scad file because I didn't want the center peak to be too high.

This is a quick design, have fun with it.
