I generally find larger tokens more satisfying in board games, and find most of the tournament reward and 3rd party tokens to X-Wing to be a bit fiddly, so I designed some over-sized tokens.
Each token is 1" (24mm) in width and 5mm thick. About the size of two quarters stacked on top of each other. I recommend that you use your slicer's pause at layer height function to print these in two colors. The flat part is 4mm thick with a 1mm raised symbol. Double sided tokens are 1/3/1mm. I've also included single sided versions of all the double sided tokens if you find yourself unhappy with the underside's print quality.
Here's a tutorial for pausing at a layer height in Cura to print in multiple colors:
I printed at a 0.12 layer height and paused at layer 35 for the single sided prints, and 8, 21, and 35 for the 3-color double sided tokens.
The double sided tokens will print without supports, but I found better quality printing with Cura's Zig Zag supports, roof enabled, Z distance 0.2, Roof thickness 0.4.
