Single Bay plano subtrays

These are trays designed to fit into the sections of a Plano 3750 series Stowaway organizers commonly found at sporting goods stores in the fishing section. The lower box provides two purposes:

1. The box replaces the dividers as it fits snugly into the space and seats on the small nubs where the divider would sit.
2. It's removable so you can take just the box with the stuff you need instead of the entire organizer.

The inserts are friction fit, and divide the space into two, four, six, or eight sections.

EDIT: I've added three more files for the upper and middle rows for those parts that are small enough that they escape their allotted space and mingle in other spaces where they shouldn't be in. (that, and the dividers tend to slide out a little too easily...)
