The model is not ultra precise, I scaled it up from a much smaller model I made before replacing the 1 with a threaded hole, but the imperfections do not affect the intention so I've left them. While the standard for dice would be 100% infill at this size would require a crazy amount of material, my example print is 20% and is heavy enough and rolls well. Definitely should use a 3 dimensional infill, grid would be very likely to fail with limited use. The model is loaded with the 1 up, it will print best with the 1 facing down.
The author marked this model as their own original creation.
