Here is my version of the insert for the board game CITIES - or rather, the individual components. I place them as shown in the photo (on top of the game board and city boards) and put the bag with the houses in the remaining space, so everything is stored relatively securely.

The design is based on an inner box size of 220x220x62mm and consists of the following parts:

• cities_citytiles.stl (128.5x65x43mm, 22g filament) Holds the 36 city tiles (including the 4 starting tiles) in 2 rows.
• cities_featuretiles (84x29x43mm, 13g filament) For the 48 feature tiles, divided into 3 rows.
• cities_players (90x36x21.5mm, 15g filament) Each tray has two compartments for the player’s components (8 pawns, 3 rings, and 1 token per color). It’s not specifically designed for the individual items, but the tray fits perfectly with the other parts. Print two of these.
• cities_cards (72x48x16mm, 6g filament) Holds the 32 scoring and 4 player aid cards.

The cities.3mf includes all parts on one printing plate.

I look forward to constructive feedback.
