Silica Gel Spool-Core Container – 4 Lid Options

Silica Gel Spool-Core Container

Keep your filament storage organized while making use of the otherwise unused space inside your filament spools.

The Silica Gel Spool-Core Container fits into the center of a filament spool and holds silica gel directly with the filament during storage.

The system includes four interchangeable lid options – two ventilated versions and two versions designed for a small round digital hygrometer.

Depending on the lid, the container can also act as a convenient spool-core stopper , making it easy to insert, remove and handle.

4 Interchangeable Lid Options

Choose the lid that best fits your setup:

Hygrometer Lids

Two lid versions are designed for a small round digital temperature/humidity meter :

- Lid Round Hygrometer

- Lid Star Hygrometer

These allow you to monitor relative humidity and temperature directly at the filament spool while still using the container for silica gel.

Vent Lids

For a simpler setup without a hygrometer, two ventilated versions are included:

- Lid Round Vent

- Lid Star Vent

The integrated ventilation slots allow air to circulate through the silica gel while keeping the beads safely inside the container.

Designed for Filament Spools

The compact container makes use of the normally unused space in the center of a filament spool.

Instead of placing loose desiccant bags around your filament, the silica gel stays directly inside the spool and can easily be removed, regenerated or replaced.

The interchangeable lids let you choose between a simple ventilated setup or integrated humidity monitoring without needing a different container.
