Here is a round or square coaster. I printed out mine in TPU but you could print them out in anything. Bar coaster can get wet and ruin your furniture. A sweating glass fills up the bottom of the coaster with the groove and then when you pick up the glass it drips. This prevents the drips and can display your favorite tavern coasters. These are easily scalable in a slicer to match any coaster you have.
