We've been using these organizers quite some time now. They give us a better overview of the cards in the game and make it easy and fast to setup.There are three versions of the organizers in STL format. A cover and a box for each size, large, middle and small. The middle size is for the infantry and the large size is for the armor, ... . The small size are for the small cards which do miscellaneous things.I've attached the openscad script as well. At the bottom you can (un)comment the right function call to generate the cover or the box. At the top you can set the right variables for the sizes.If you want I can always print some via my 3DHub : https://www.3dhubs.com/antwerp/hubs/kim (just click on "get a quote from this hub" and leave me a message.
