This is the
large version of my regular
gaming D20 in the 'Radial' design family of dice.
The numbers on this die are arranged so that the sum of the numbers on two opposing sides is always 21. Great care has been taken to ensure that the die is fair and well balanced, and therefore throws should not be biased.
The die is about 40 mm (1.6") high. This size is best suited for printing in plastic. There is also a
smaller version available which will work better when printed in metal.
A version of this d20 with the numbers arranged in a spindown pattern, so that it can be more easily used as a life counter in games such as MTG, is can be found
here.
For other dice in this design family, please have a look at the
'Radial' category in my shop.
To enhance the look of the die, and to make the numbers on the die stand out more, you can color the numbers using acrylic paint and a fine brush. Because the numbers are raised above their background plane this is quite easy to do.
