Container System Reusing 3DfilsCardboard Cores

This modular system is designed to give a second life to the cardboard cores from 3Dfils filament spools. The model includes several printable parts that fit precisely into the core’s dimensions, allowing you to build customizable containers for organizing tools, parts, or other small items.
Each module is stackable, can be printed without supports, and assembled without glue or screws. Multiple configurations are possible thanks to the interlocking system. This is a sustainable, practical project for any maker looking to reuse filament waste efficiently.
