Not sure how to market these over other spell slot trackers, so, idk, try looking at the pictures. Not sure if this is obvious or not, but you flip a token over to use the spell slot.

Tokens for spell levels 1-9 are available as well as a screw-top container that is big enough to hold a full caster set of 22 tokens.

Printing:

Almost any settings should work. No support, no adhesion. They will probably print fine with as low as 10% infill or possibly less, but I've never tried with less than 20%. Print tube and cap the same way.

Takes 7 Hrs, 45 Min, and 35 Grams of material.

Finishing the Tokens:

   1: Color in the details. You can use sharpie, but paint looks much better, a paint marker works perfect. I reccommend using something fine-tipped for the lines, as that makes it easier to remove the excess, I especially had issues with the level 9 token, as you can see.

   2: Sand the face with 150 grit sandpaper until excess sharpie/paint is no longer visible.

   3: [Optional] Sand the face with 300 grit to give a smooth finish.

Picture is Hatchbox white PLA, with Sharpie brand black paint marker, using the optional 300 grit sanding step.
