These Crypto Coasters are suitable for the boardroom or the living room. Choose five coasters for
the default caddy, or print the larger caddy that holds six. Or, print two of the shorter caddies
and print ten coasters! More crypto currencies will be added soon, so come back often. I recommend buying some felt and spray adhesive from your local hobby store. The caddy is actually designed to accommodate five (or six) coasters with felt on the bottom of each coaster. You can also put rubber feet or another piece of felt on the bottom of the caddy.
No support necessary. Print at .2 or better with recommended 60% infill or higher. The reason is they will get wet and you don't want to encourage any water intrusion. Also, they should have some weight to them in my opinion.
