I played a lot of Dominion and its first couple of expansions when they came out. I also took them to enough friends’ places that I grew frustrated with the inefficient storage in the boxes. So, I built a foamboard insert for my Dominion box and wrote a python script to generate dividers for the base game and the first 3 expansions. Since then, I have maintained and improved this script and added all Dominion expansions to date with the help of a lot of volunteer contributors. I also wrote an online web version of the command line script.
