These are a set of coasters based upon the perks in Call of Duty Nazi Zombies. This is a remix of another user's set of 4 coasters that were painted to produce the color combinations. The main differences between mine and the original design:
I added cork bottoms after printing to the coasters, but this is not required. Please see your slicer's documentation about changing filament colors mid-print to achieve two colors in your prints. You will notice the perks I printed have a colored bottom and then white text/decorations on top.
Lastly, this is a remix of another model on Thingiverse. The Printables upload interface does not support ticking the remix box and inserting a link to the model, so please see below for the model I remixed (I posted this on thingiverse if you search you will find my model too):
