Twilight Struggle Player Tray

I stole the idea from http://www.thingiverse.com/thing:135286. I printed it out and, at least with the Replicator 2, it was a tad too wide for the original box. I considered trying to adjust his design, but instead redesigned. This player tray with its lid to keep the nibs/chits from tossing around in the box should sit flush with the card tray or a mm off.
