The Great War and Expansions Organizer.

thingiverse

This organizer is specifically designed for The Great War Centenary Edition, the Tanks expansion, the French Army Expansion, the Whippet tanks mini expansion, and three sets of the French tanks mini expansion. The player trays shown are tailored to hold 24mm blocks representing infantry, machine guns, and mortars (Columbia/Worthington style). You can obtain the block labels required for these at https://boardgamegeek.com/filepage/120910/simple-set-downloadable-lables-20mm-blocks and https://boardgamegeek.com/filepage/184153/french-block-labels-based-red-poppies-art. These trays feature designated spaces for each special personnel mini type, making setup effortless. In addition to the player trays, there are separate compartments designed for the infantry, machine gun, and mortar minis that come with the game. Although I haven't printed them yet, they should fit perfectly in their allocated space. These organizers are carefully crafted to fit within both the Centenary Edition box and the French Army box. However, due to the Tank expansion box being slightly larger than the others, using it will result in a less-than-tight fit. The two tank trays are meant to be placed with the board, rules, and player aides in one box, while everything else goes into the other box.
