About this 3D model
https://youtu.be/u4XNL-uo520 I reverse engineered these dice for two color 3d printing. I used Devin's (Make Anything) idea of printing the dice flat and then fold them into place. They are each 20mm. Note: The magenta dots have additional dots left and right to help align on your build plate. You can scale the objects to 80% to get 16mm
