Inventors of the South Tigris Insert

Inventors of the South Tigris - Storage insert holds sleeved cards (may need trimming to fit).

Added an STL for the expansion content. This is just a simple box container that fits in the gap above the other tiles next to the cards. I then trimmed the score sheets so they fit above the new player board (these are layered 4 deep side by side). This causes a slight cover lift but still everything fits in one box.
