I printed jhoarty's Crypto Coasters (https://www.thingiverse.com/thing:2876513), and they are awesome! I thought the holder could be a bit more fun. So I designed this as a compliment. The one i printed I left more room in and the coins jiggle a bit, so i did one smaller but didn't print it so can't guarantee a fit.

I had a multi-color filament "Rainbow Gradient" from CC3D (purchased on Amazon). Did this at 205c .12. All in was about at 15hr print.
