Ikea Kallax Spoolshelf

I encountered a minor issue regarding storage for all my filament spools without cluttering our workshop with numerous boxes. Consequently, I designed a small, modular shelf system that can hold up to four spools on a single rail. Furthermore, the taller rear version allows for expansion to accommodate eight spools.

It was crucial to me that the design be entirely 3D-printable and require no additional screws or fasteners. The model is fully printable.

For the crossbars, I recommend a minimum infill of 50% to ensure sufficient stability when holding up to approximately 4 kg.
