Pioneer Days Box Organizer
I couldn't find an organizer for Pioneer Days, so I created one - my first from scratch design ever.
Note that I kept the cardboard punch boards and put them under the original cardboard divider (see picture). If you don't have that, then you might need a spacer or some foam to make the organizer completely fill the box.
I made the trays using Deck in a Box: https://deckinabox.sgenoud.com/
I added the text cutouts using Tinkercad: http://tinkercad.com
