By adjusting the parameters in the SCAD file you can create any number of Aember tokens that are different from each other and everyone else's tokens. The unique designs are Julia Sets.

I printed my tokens with silk gold filament but would be interested in seeing the results with a transparent filament. The photograph shows printing using a 0.4mm nozzle; I will be printing again once my finer nozzles arrive.

Note that if the top texture resolution is the same as the nozzle diameter (as is the default here) then your slicer may throw away detail. With Cura 4.0 I found that scaling to 102% preserved detail (look at the top layer in the preview to check).
