The file 'Encyclopedia Chest Topper 3D Printer Model' is (stl) file type, size is 6.3KB.
I really liked BoardgameCreations' insert for Encyclopedia (https://www.thingiverse.com/thing:5633951) but wanted to use the cardboard chests that came with the game. This topper sits across them to allow for vertical storage so that none of the contents fall out as the chests are slightly shorter than the surrounding trays. I've only included the chest topper file, everything else should be used from the original insert but now don't print the 2 resource trays and 2 money trays.
My print in the photo is hashed as I print without bottoms/tops/walls to save on filament.
