Marvel Crisis Protocol - Dice Tray/Dice Plate

I've built a dice tray for Marvel Crisis Protocol. This dice tray allows you to roll ur dice in the large area and then cleanly add the crit-rolls in the small area, without mixing them up. You can then show your opponent the results of the roll on the small tray above.

I later bought some felt and glued it into the trays so the dice would roll more quietly.
