60g High-Airflow Silica Gel Container for Filament Spools

60g High-Airflow Silica Gel Container for Filament Spools Keep your filament dry while it is stored. I designed this reusable desiccant container to fit inside the center of a filament spool and provide as much airflow around the silica gel as possible. Instead of using only ventilation holes on the outside wall, the container allows air to reach the silica gel from multiple directions. The body is highly perforated around its circumference, while both the bottom and screw-on lid are ventilated. A central perforated air channel also allows air to reach the silica gel deeper inside the container. The result is a compact container with a measured capacity of approximately 59.6 g of silica gel. Features ≈60 g measured silica gel capacity Designed for the center of filament spools High-airflow perforated body Ventilated bottom Ventilated screw-on lid Central ventilation channel Radial ventilation pattern Reusable and refillable Threaded lid No supports required Easy to print Suitable for indicating/rechargeable silica gel beads Helps keep filament dry during storage Airflow design The container uses several ventilation paths instead of relying only on holes in the outer wall. Air can reach the silica gel through: the perforated cylindrical wall the radial holes in the bottom the radial holes in the lid the perforated central air channel This increases the exposed area of the silica gel while keeping the beads securely inside the container. Capacity The prototype was filled and weighed with silica gel beads. Measured silica gel capacity: 59.6 g The exact capacity may vary slightly depending on the size and type of silica gel beads used. Dimensions Outer diameter: 50 mm The container was designed to fit inside the center opening of common filament spools. Please measure the center hole of your spool before printing.
