This is a box insert for Pioneer Rails designed to keep all the components organised in the box and make setup faster.

It was designed for the “Essential Edition” (the deluxe Kickstarter version) but will work for the retail version too (there'll just be some empty sections).

Spaces are available for the pencils and eraser that came with the game.

The insert can either be printed as a single piece (SingleTray.stl) or as four separate parts for smaller printers. For the split version, print one of each file.

It should fit sleeved cards up to 65x91mm, but I haven't tested this myself.
