Tang Garden board game has a great organizer for all the large bits, but only bags for the small bits. I designed this print in Tinkercade to hold and organize those small bits. You can see how it fits in the box in the photos provided. The tray also helps keep them in place when storing the game vertically. The only small bits not able to fit are the 4 square character tokens, which I store with the bridges. This was designed for the retail base game only, as that is what I have.

NOTE: The organizer in the pics is slightly different than the STL provided. I have made the text less deep (in order to improve readability of the small text) and rounded off the "20" coin corner to make it look cleaner.

Print instructions

Machine: Prusa Mini+
Layer height: .20 Quality
Filament: Jessie PLA 1.75

I would do a color change at 2.6 layer height to help the text stand out.
