I'm starting to think that who ever came up with this list sat down and went "hey you know what would be fun? Let's make a list of 31 words that get slowly harder and harder to design dice off of" open?! Seriously?! Well I gave it the old college try. I liked that this one had a bit of a mechanical aspect, fitting together like a puzzle.

Available in raw resin $10 and painted $20 (last picture is an example of a random unpainted dice)

All my dice are made from solid 3d printed resin. The painted versions are sprayed with 3 layers of clear coat so they are usable but I would suggest rolling them on a soft surface to avoid chipping or wear and tear on the paint job.
