These dice can be used to determine critical hit results when playing Battletech: Alpha Strike without needing a lookup table.

For improved per-face consistency, texture, and fairness, each die face is printed individually and must be assembled (the pegs snap together and don't require glue).  This also makes it possible to change the filament and color the faces without an MMU.

To use the dice, simply roll them together and use the result with the highest number.  The possible permutations are the same as using the regular lookup table.
