Filament Storage Desiccant Holder

Model Description (Updated Section)

This desiccant holder is designed for filament storage cereal boxes (4 L containers) commonly sold on Amazon and AliExpress. It provides an easy way to keep silica gel or other desiccants inside the container to maintain low humidity and dry filament during storage.

The holder keeps the desiccant contained while allowing good airflow, helping moisture to be absorbed efficiently without the beads spilling into the container.

Features

• Compatible with 4 L cereal storage containers
• Works with Amazon filament storage boxes
• Also fits many AliExpress cereal container dry boxes
• Supports many 1kg spool sizes (Max Spool Diameter is 200mm)
• Holds silica gel beads or other desiccants
• 2 mm ventilation holes for airflow
• Prevents desiccant beads from escaping

⚠️ Note:
The hole size is 2 mm, therefore use silica gel beads with a diameter of 2 mm or larger to prevent them from falling through the holes.
