• As I always had issues with glasses slipping from 3d printed coasters, I've designed a simple solution: the circles around the cat draw are higher than the rest of the coaster, so it keeps the glass from moving out of the coaster
• big coaster, 106mm diameter, but you can scale it up more if you have even bigger glasses. (tested with the biggest I had :) )
• Use layer height 0.2mm (also for the first layer) and change colors at layers 11 and 14.
   

Happy new year !
