(6 pack) Sterilite Small Gasket Tote, 5 Gallon WaterProof Plastic Storage Bin with Lid, Gasket Seal and Durable Latches, Black

I purchased this 5-gallon Sterilite gasket bin for a specific technical use: keeping my 3D printing filament bone-dry. While many people use these for holiday decorations or as a general organizer, the airtight seal makes it a "pro-level" dry-box for makers. It comfortably fits four standard 1kg spools. ​The hinges and latches are heavy-duty and provide the perfect amount of pressure to fully compress the gasket seal. To ensure the environment stays dry, I keep a small container of silica gel beads inside. This actively draws any remaining moisture out of the air immediately after closing the lid. ​By combining this airtight bin with the silica beads, I've been able to keep my internal humidity at 15% or lower (monitored by a hygrometer). This is the best way to prevent brittle filament and ensure high-quality prints. It is far superior to standard bins that lack a proper seal. Highly recommended for any serious hobbyist!
