With the popularization of 3D printing technology, the usage of 3D printing filaments has also increased sharply. Among them, FDM 3D Printing has gradually become the mainstream. The filaments used in FDM 3D printing are mostly filaments with spools,which occupies a large space and certain weight, and is inconvenient to pack and transport, resulting in higher transportation costs. The production cost is high and would cost high waste of resources and environmental pollution when you throw away the spools that cannot be recycled. To protect our environment, this detachable and reusable espool was designed.

Assembly instructions:
1. First, distinguish the front and back of the espool, the side with grooves and label slots is the front side, and the smooth side is the back side;
2. Align the 3 pieces of the small piece with the fixing holes and insert them into the back of the disc;
3. Put the filament refills into espool;
4. Align the other disc with the fixed pillar and press and splice.

Environmental friendly:

The product can be disassembled and recycled and is environmentally friendly; the packaging bag is made of biodegradable PBAT and PLA biological materials.
