I have a cork coaster that I got from a tour of UAH and decided to make my own coaster. Ill probably glue the other one to the bottom to stop it from sliding around. Fingers crossed for my application. Ill upload a picture once I get a chance to print it.

The version 2 stl is with the logo as an ident instead of an extrusion. In order to keep most of the detail you need to use the 0.12mm setting or an adaptive setting that can adjust for the smaller lines at the top of the print.
