• Specifically designed for empty spools of filament with hollow cores, this product repurposes discarded filament cores into a practical filament storage/anti-humidity box when paired with 3D-printed top and bottom lids.

• The top lid features a non-slip texture and an easy-to-grip handle for convenient opening and closing, while its airtight seal provides excellent dust-proof performance. It’s ideal for storing loose filaments, small tools, or as a desktop storage container.

• This design supports seamless, support-free single-piece printing, with a simple structure that’s beginner-friendly. It’s compatible with PLA and PETG filaments, and the dimensions can be customized to fit various core sizes as needed.

🛠️ Printing Recommendations

• Layer Height: 0.2 mm

• Infill: 15%–20%

• Wall Thickness: 2–3 layers

• Recommended Materials: Both PLA and PETG are suitable; PETG is more durable and less prone to cracking.

• Support-free printing—simply place the part directly on the print bed for successful build.

📌 Application Scenarios

• 3D-Printed Filament Storage: Transform discarded filament cores into support-free filament storage boxes that offer dust- and moisture-proof protection while reducing costs.

• Desktop Storage: Perfect for organizing screws, small components, jewelry, stationery, and other items—multi-functional and versatile.

• Eco-Friendly Upcycling: By repurposing discarded filament cores, this solution minimizes waste and provides a low-cost DIY storage option.
