I originally ran across this model on Printables at [https://www.printables.com/model/102725-dd-class-coasters](https://www.printables.com/model/102725-dd-class-coasters), but the original file is on thingiverse at [https://www.thingiverse.com/thing:4901671](https://www.thingiverse.com/thing:4901671). I printed the ones from printables but found it was missing a few classes and the coasters were just too small and since it only have the word and the class symbol cups would rock back and forth. So I scoured the internet to fins the class SVG files as well as the Dungeon Master SVG and created these using the customizable coaster link from thingiverse and SCAD. These coasters are approximately 100mm across, however if the size doesn't work for you please feel free to change the design to your liking. If you need any of the files needed to create you own, please reach out and I will do my best to get them to you.
