FATE Dice!

This is what is called a Fudge dice for the FATE RPG system. The game mechanics revolve around rolling 4 fudge dice to determine if an action was successful.

I recently obtained Diaspora, a tabletop RPG that uses FATE and I created this dice (and the d12 version which you can find here http://www.thingiverse.com/thing:870967) in honor of the game.
