Average D6 Shell Dice

A brand new shape for the Average Die with numbers on each corner and a hollow structure.
To find the result of this die, you have to make the average of the four numbers pointing upward. For instance, 8 + 10 + 1 + 1 = 20, thus the result is 20/4 = 5. The positions of the results (from 1 to 6) match those of a standard D6.
