I remixed the Bang Storage Box by commender1 (https://www.thingiverse.com/thing:5774216) because I have all the expansions and needed to change some slots for the cards. Moreover, I use sleeves so I customized his model.

I printed the BANG! letters in red and glued them to the holes in the box. I used the setting "Horizontal Expansion" in Cura to add a -0,4mm offset to let them fit properly.

There is space for these expansions:
Bang! Base Game
High Noon
Dodge City
A Fistful Of Cards
The Valley of Shadows
Wild West Show
Gold Rush
Armed & Dangerous
The Great Train Robbery

My printing bed was not big enough to print the whole box, so I divided the box and the lid in two parts (I uploaded also this files in case someone has the same problem). I put a red plaque (placca congiunzione) under the lid to ensure stability, this is only needed if you have to split the print.
