Formula D Dice

I couldn't find where the dice are sold any more so I created a set in Freecad.

The dice for the gears in Formula D are standard sizes but only certain numbers can be rolled.
Yellow d4 1st gear 1,1, 2,2
Orange d6 2nd gear 2, 3,3, 4,4,4
Red d8 3rd gear 4, 5, 6,6, 7,7, 8,8
Green d12 4th gear 7-12 x2
Purple d20 5th gear 11-20 x2
Blue d30 6th gear 21-30 x3

This is my first upload and I've been trying to teach myself Freecad so I apologize if there are errors.
