Product design concept:

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.

 Possible reason


The latch structure is difficult to insert

Mess up with front and back side


The concave side is the front side, and the smooth side is the back side

When changing filaments, the remaining filaments are scattered

Change filaments without using up

It is recommended to use half or more before replace it. Before changing the filament, use a band to pass through the hollow part to bind the remaining filaments.

The latch structure is difficult to pull out

Harder to hold by hand

Use tools, or use greater force to press and pull out
