The coasters have a diameter of 90mm. The stands are designed for 6, 8, 10 or 12 coasters.

Best printed using a multi-material printer. In this case you can print the logo on both sides (one flat and one embossed). A pre-coloured 3mf file is included.
Otherwise you have to swap the filament after 2mm.

The stand/holder is best printed with 3 walls. I used ironing.

I originally posted this model at Printables.
