I have seen may different custom pieces for this awesome game. I collected a few and then made an insert for my personal customization of the game.
These are external STLs that are required for the insert:
Print 1 of everything except for print 5 of the army tray and lid, and four of the Wow_LoyalityMarker_Holder_v3x4.
Each insert piece as a letter on the bottom that you match up.
The author marked this model as their own original creation.
