Modular Filament spool Shelf/rack

Modular Filament spool Shelf/rack I designed fully modular 3D printable side panels for building filament storage shelves. Each level can be stacked on top of another or used independently on the floor. For additional reinforcement, you can insert a threaded rod between layers, or connect them using a tube. A wall-mount bracket is also included. All holes are modeled with slight tolerance, so no drilling is required. The model prints support-free. Features Modular design – stackable levels Can stand on the floor or be wall-mounted Layer connection via tube (Ø 20 mm) Optional reinforcement using threaded rod (M8 / Ø 8 mm) All holes have tolerance No supports required Print settings Material: PET-G Infill: 15% Crosshatch Layer height: 0.24 mm Perimeters: 3 Material use: ~ 500 g per shelf No supports needed ⚖️ License This model is my original work Only personal use and private printing is allowed Commercial use, selling printed models, or modifications for resale are not permitted 🇨🇿 M
