2. Package Contents
Please verify that all components are present before beginning assembly:
- Fabric Cover with transparent front panel
- Reinforced Iron Frame Bars (various lengths)
- Plastic Connectors (for frame assembly)
- Desiccant Packs (4 count)
3. Setup and Assembly
Assembly of the filament storage box is designed to be straightforward. Follow these steps carefully:
- Unpack Components: Carefully remove all frame bars, connectors, the fabric cover, and desiccant packs from the packaging.
- Assemble the Frame: Connect the iron frame bars using the provided plastic connectors. Ensure each connection is secure. The upgraded connectors are designed for a smoother fit, but firm pressure may be required.
- Build Tiers: Construct the two tiers of the rack as shown in the diagrams. Pay attention to the orientation of the connectors to ensure the shelves are level and stable.
- Attach the Cover: Once the frame is fully assembled and stable, carefully slide the fabric cover over the frame. Ensure the cover fits snugly. If the cover is difficult to install, double-check that all frame bars and connectors are securely and correctly joined.

4. Operating Instructions
Using your YOOPAI Filament Storage Box is simple and designed for convenience:
- Load Filament: Unzip the front panel of the cover. Place your 3D printer filament spools onto the shelves. The rack is designed to hold various sizes, including standard 1KG rolls.
- Utilize Desiccants: Insert the provided desiccant packs into the designated mesh pockets inside the cover. These help absorb ambient moisture to protect your filament.
- Accessing Filament: The high-quality double zipper and transparent PVC window allow for quick selection and easy access to your filament rolls without fully opening the entire cover.
- Secure Storage: After loading or retrieving filament, ensure the zipper is fully closed to maintain a dust-proof and splash-proof environment.
Important Note: This storage box is intended for organization and short-term moisture reduction with desiccants. It is NOT an active filament drying box or dehydrator.

5. Maintenance and Care
To ensure the longevity and effectiveness of your filament storage box:
- Cleaning the Cover: Wipe the fabric cover with a damp cloth as needed to remove dust or spills. Avoid harsh chemicals.
- Desiccant Replacement: Monitor the condition of your desiccant packs. Replace them when they show signs of saturation (e.g., color change if applicable, or reduced effectiveness).
- Frame Inspection: Periodically check the frame connections to ensure they remain secure and stable.
6. Troubleshooting
- Difficulty Installing Cover: If the protective cover is difficult to install, ensure that all frame connectors and tubes are securely connected and fully seated. Loose connections can alter the frame dimensions, making the cover fit improperly.
- Filament Still Absorbing Moisture: This storage box is designed to reduce moisture exposure with passive desiccant absorption, not to actively dry wet filament. For heavily saturated filament, a dedicated filament dryer is recommended before storage.
