Store and Feed Four Spools Simultaneously — All Kept Dry

For makers running multiple printers, AMS systems, or a print farm, the 4-spool filament dry box is the smart way to keep your most-used filaments dry, organized, and feeding simultaneously. Four independent PTFE feed ports let you run four printers — or four AMS input channels — directly from sealed dry storage.

• Humidity Display: Built-in digital hygrometer — real-time humidity and temperature monitoring
• Feed Ports: 4× PTFE-lined feed ports — feed up to 4 printers or AMS channels simultaneously
• Seal: Airtight lid with silicone gasket covering all 4 chambers
• Desiccant: 2× large reusable silica gel desiccant packs included
• Spool Bearings: Smooth-rolling bearing system for each spool for tangle-free feeding
• Compatibility: All standard 1kg spools from any filament brand
• Material: Food-grade ABS and PP

Ideal for Bambu Lab multi-printer setups, OctoPrint print farms, or any makerspace running several printers side by side on different materials.
