1.25 inch base diameter - 22 & 25 degree folding cones

Used to make coin rings with a folding die. So far my expereince has been postive and the PLA is softer than the coins metal thus saving the detail of the coin.

I printed them at 100% infill but you could probably get away with a 50% complex infill pattern and maybe upping the wall count for durability.
