You can make Company Leader for free! Well, of course you have to pay for printing...
All the files you need to build the components for this game can be found in the download section. And, to save on printing costs, there are also files with a less colorful presentation (marked as ink friendly).
In the view on the right side, there is a list of components which link to a description in this view about how to build them. You do not need all of the listed items to play the game, but you are given various options for your DIY project. See the game rules for a complete list of necessary components.
