Edit 3/18/2020:
On request, I've created a 4th coin with a star pattern. Maybe print it with some sort of Platinum coloring or theme? I dunno. Do with it what you will. :)

Three coin patterns for use with DND, board games, pretend play, or whatever tickles your fancy. The coins are designed to print at 25 mm diameter each. Any smaller and you're likely to lose details. Any larger and I doubt the pattern will print properly on the underside unless you're a wizard with setting up custom support material prints. On that note, if you print at the 25 mm size, you should have no need for supports! I designed the patterns on the coins to not have large gaps, so even the underside prints cleanly without sag.

I designed the "sun coin" with gold silk filament in mind, the "moon coin" with silver, and the "earth coin" with copper. You're free of course to use whatever you want, since these coins are designed to be generic in use. Given that, there are no numbers or markings on the coins to denote denomination or value.

Lastly, be careful when removing these from the build plate. I use a scraper to pop my prints off and found that maybe 1 out of every 10 of these would end up cracking or splitting on the raised lip along the edge.

Enjoy!

EDIT:
For anyone having scaling issues, please try the "scaled" stl files. When I pulled those into Cura, Cura didn't have to auto-scale.
