I designed a numerical balanced D20 die that uses numbers as objects for multi-material coloring rather than paint by number like other dice.

All numbers are skewed to be aligned flat with the bed for best print orientation when printing in multi-materials. The dice body is name D20 and the numbers are named correctly or use a "_" to denote which part of the number it is.

One click painting, just select object D20 to change the body color. Slot 1 for numbers and Slot 2 for body.

All test prints were done on a Bambulab A1 mini in PLA and PETG and the max angle is 48 degrees. Tested at 0.12 and 0.16 layer height, 2 walls, 100% infill, and 8mm brim.

If you have great bed adhesion this dice can be printed in PETG/PLA mix. Brim will want to be letter color instead of body color though, if you can trick the slicer please upload a new profile.

Numerically balance D20 die is based on a paper by Bosch, Fathauer, and Segerman. The point of ordering the dice in this manner is to keep the average roll at 10.5 regardless of any defects in the dice. Vertex sums average 52.5, face sums average 31.5, 20 and 1 are on opposite faces, and average roll over enough time is balanced at 10.5.

Commercial use permitted with attribution. D20 Dice are very common, I just wanted to make this dice easier to print in FDM rather than resin.
