I wanted to create the geometry each of dice, using logic and geometry (except for the D6 that a bit easy). No search on the web, only study the dice and some construction line in wireframe stye, that I have transform in surface and then in solid, except for the D6 and D10, that I have modelled them directly in solid.

I have printed it in TPU, but it can surely be printed in PLA.

If you print-it on scale 1/1, the d20 is around 1-1/2 inche (38mm).

You will surely need to rotate the dice 90 degrees in the x axis to print-it flat on one of his side. My bottom plane plane in my drawing software is not the same as per my slicer.

Next thing to do on it, put some paint in the number.
