Stackable Filament Storage with Snap-On Lid

This is a 3D printed filament storage system that I designed to hold and organize 1kg spools. The design features diagonal cutouts on the top and sides, which gives it a clean, modern look while allowing you to easily identify the filament color and see how much is left on the spool. One of the best features is the snap-on lid mechanism. The lid is designed to click directly into place without the need for extra hardware or tools, making assembly quick and easy. These storage units are fully stackable, providing a practical and space-saving solution for keeping your workspace tidy.
