Made to be printed face down on a textured plate, giving it a nice top finish.

These are designed to be used with a 2mm thick, 100mm diameter cork coaster with adhesive backing. I used these ones:

I print these as a set of 4 and have included a holder as well. For the bottom of the holder I use these rubber stops:

Both the cork and the rubber stops give the coasters a nice feel, and help to prevent any sliding around.

Please note: You may have to adjust some settings slightly to get your printer to fully close the gaps between colors, these are just the values that work for me.
