I put the ability counters from sploooosh (https://www.thingiverse.com/thing:4267640) onto a base to improve contrast when put onto a card/table and also help picking it up.
Printed with a single extruder with PrusaSlicer's color change feature. PLA with a 0,4mm nozzle. Think Arachne really aided the quality there.
The stl files did the job for me. Step files looked weird in the editor and I'm not really exerieced with them, maybe they help you anyway. Also the Shapr3d files are attached in case you have it as well.
Also take a look on my matching mana counters https://www.printables.com/model/275071-mtg-mana-counters
