Coaster with hexagon top

Though I found a lot of coasters with a similar design, my wife wasn't satisfied, because they were all very hard to clean. So I designed my own ones, with a low height at all, and the hexagons are only 2 layers high, when printed at the default layer height of 0.2mm ;-)

UPDATE 6/17/2023:
I added a tray for up to 13 of the coasters
