Sealed Filament Case, Spool Storage Box

To save storage space, this spool box is designed to fit the official spool size as closely as possible, leaving just enough gap for a filament clip

The lid fits snugly, with a press-fit latch for easy opening and closing

Note the installation direction of the latch, the notched side faces inward:

I've updated the latch to include a foolproof design, preventing the box from cracking if forced in the wrong direction

The second print profile features only a round transparent window in the middle and requires an AMS

The third print profile uses random seams, which may result in minor bumps on the surface but prevents the lid from not closing properly or affecting the seal due to overly prominent filament seams with some materials

Three types of labels are provided by default: PETG, PLA, and blank ones, and the text on them can be customized

I personally prefer writing on paper, then printing the blank label transparently and inserting it behind a clear film

Matching stackable expandable filament rack, a 118g lightweight rack for perfect storage:

The circular ring at the bottom of the box can snap into another dry box model I designed:

If you don't have a suitable filament clip, you can print this one:

I've also created a new version with a built-in turntable and PTFE connector, which can be hung directly on the printer for filament feeding:
