These boxes are inserts for organizing small parts inside Hatchbox filament boxes. These are designed to fit 4x4 in the box so you can do any combination of sizes that adds up to that.

This is a great accessory for the shelves/drawers I designed for the Hatchbox boxes: https://www.thingiverse.com/thing:4607627

These parts are not a super tight fit in the box since I wanted to leave enough room for the side flaps to fit in place when closing the box.

I only included the box sizes that I have printed and used, but I made this a Customizer so you can get any size you want.
