Two weighted dice, each made of two parts, the base and the weight. One is weighted to roll 20, and the other is weighted to roll 1. I split them into separate parts so that it could be printed on a resin printer as well without having to deal with cavities. This is remixed from AtomicDice's 7 Piece Dice Masters Set. I used the d20 to model this. There was an issue I had printing it the first time where one of the weights didn't fit in place. It should be fixed now.
