Simple print-in-place double sided coasters in three different sizes - for cups/glasses/bottles, for plates/jugs and for pots/large bowls. For best results it must be printed at 0,15 or 0,20 mm layer height. These on the photos are printed with 0,6 mm CHT nozzle, so 0,4 mm nozzle will give even better results.

PS: It is very relaxing when you crack it ;D
