GSW Miniature Backpack Rails

I really appreciate the GSW backpack for transporting my miniatures, but I'm very annoyed by the fact that the laser-cut rails constantly fall out. Additionally, the trays sag because the rails don't fit properly at the back. These printable rails have a small tab at the front and back that ensures they cannot fall out by themselves - even when bumped or shaken, they stay in their place. The rear rail was raised slightly so that the trays now lie properly.Boost MeIf you like my design, please feel free to leave me a boost if you'd like.
