When starting my own cache, i modeled my own geocoins for this for the first three finders of the cache. If you want to add the ID of your cache to the coin, ideally use PrusaSlicer 2.6 alpha or your favorite CAD program (a STEP file is also available for this purpose). The coin is designed to be printed in three colors.
Printing without supports, Infill: 15%.
