Caffeine Coaster with Bottom

A simple remake of Hobsie's Caffeine Coaster.

Added a bottom so that the water droplets have a place to go instead of my wood countertop. Admittedly, this is probably going to be a breeding ground for bacteria, so maybe giving it a soap bath every so often probably isn't the worst idea.

(Note that this problem is also in the small letter holes of the original design, so that should also probably be washed)

You can see the fusion360 design at https://a360.co/49jlfVz and I've uploaded the fusion file if that doesn't work.
