A dedicated desktop storage rack designed specifically for small spools of filament, with all components 3D-printed—no need to purchase additional parts like metal linear guides. Simply print and assemble for a lower-cost solution.
It uses eight M3 screws for secure assembly, ensuring smooth, jam-free rotation of the printing axis and a sturdy, vibration-free structure. Each rack can hold two 250g spools simultaneously, featuring a symmetrical left–right layout that significantly saves desk space. A large-diameter circular base provides solid support, keeping the rack stable and preventing tipping, while perfectly accommodating most standard 250g filament spools. This makes it an affordable, easy-to-build, and highly practical filament storage solution for 3D printing enthusiasts. Note: Please note! Enlarged prints can accommodate up to 1,000 grams of filament.
