Finally, a multifunction coaster!
For Schematic Symbol Reference Guide PCB Coaster
Definitely like this coaster, it works well although I'm a little hesitant to use anything other than plastic or glass on it. I would think that some of the rough, earthenware cups I have might scratch the really excellent silk screen.
Personally, I intended to make a 3D printed frame for this to get it off the surface and add a little protection to the visuals.

I would love to see the 3D print!
