Space Hulk Doors

There's a bunch of cardboard doors in Space Hulk, and in the original game, they come with plastic stands to hold them upright. The problem is, I don't have any of those stands. So I thought of an idea: metal binder clips are very cheap, around 12 for $1 at dollar stores. The black metal part is perfect for the base.

These are the doors that come with the game.

A typical small black binder clip.
Put the clip on the bottom of the door.
Take the silvery metal hinges off and the binder clip becomes a door stand.
