Summary

A simple, frugal coaster. It saves material in the middle where your cup or mug wouldn’t touch the table anyway.

The size can be changed in the customizer. More can be changed in the SCAD file.

Now with a working customizer… (I had to remove non-ASCII characters. Oh well.)

How I Designed This

Inspired by, but not actually based on, ryanthecoder’s drip tray.

There is some design history available at my github repo.
