I was unhappy with the cardboard insert the game came with, so I decided to make my own. It's by no means perfect, but It should keep your miniatures in one piece and your sleeved decks in one spot. Feel free to improve on this if you want, as long as you're offering the models for free. And please post a comment or picture if you actually use these files. This is my first public model, so please be gentle. 

I might make more inserts for the other Underworlds boxes I have.
