The boardgame Mosaic - A story of a Civilazation has so many player pieces that I thought of organizing a storage box that you can also use during gameplay!
File contains two plates: one for the player board and one for the lid.
Player Board:
Storage Lid:
If you would like the pieces to be snug just change the X&Y scale down to 100% or 101% (Leave Z scale at 102%). Current Scale is 102% for a nice loose fit.
