Century boardgames - 3 games 1 box inserts

Recent change (8/30/19): I split the resource tray into two doublets so that all trays will fit at the same level now. You'll need to print two of them.

As of now, this design is functional. The components fit. The cards, in bags, fit on top. And the rules and player mats fit on top of everything else. However, the design is not really optimized. There are no boxes for cards. There are no lids, so the box can't be stored on its side.

Walls are 0.8 mM to save on time and filament. T
