=================================

Cold drinks in warm/humid environments tend to get a lot of condensation on the outside of the glass.

This coaster traps the puddle of water under the glass.

I'm still fiddling with it to optimize it, but this works well enough that I'm releasing it.

Made it in Sketchup, model included. The pins are a component arrayed along a spiral, so you can fiddle with the pin details (size, shape, etc) and the spacing along the spiral, as well as the spiral details.
