Civlization - A New Dawn Insert Lids

I remixed tvkili's game box inserts to add some lids to the player and wonder storage boxes. With the other organizer pieces fitted into the bottom of the box, the instruction booklet on top of that, and then the four corner boxes and square wonder box on the top, these lids fit snug, although they only use the friction of the fit to keep them in place, so they can still pop open. Because of that, I designed some little spacers (printed with 15% infill) that use the pressure of the box lid to help keep everything from shifting around, even if you turn the box upside-down.
