A remix of ahm427's Avatar the Last Airbender Four Nations Coasters to make the coasters flatter, thinner, better suited to multi-color printing, and increase stability of drinks placed upon them.
To operate, simply place the coaster between a beverage (or water) vessel and a surface which you wish to protect, or you determine needs more ATLA/TLOK theming. That's it, a coaster is not that complicated. You could probably use the box your filament came in as a coaster too, but this is for people with both a 3D printer and class, the type of person who needs, who deserves, a proper coaster to protect their table.
Each coaster is 3mm in height: the first 2mm is the base, the top 1mm is the logo and boarder. Keep in mind the thermal properties of the thermoplastic you print these coasters with when using them with hot drinks. Also, printing in a water-soluble filament is not optimal for the longevity of the coasters.
Each coaster took me about 2 hours to print, your results may vary.
