Spool hanger for shelving rack

Design Concept This model is designed for convenient storage and access to 3D printing filament spools. Its hanging mechanism securely holds the spool on any standard shelving rack while allowing for easy rolling. Uses Primarily used in setups where space is limited, this spool holder helps organize multiple filaments, enhancing accessibility and workspace efficiency. Mainly used for TPU printing. Printing Recommendations Requires a sturdy material such as PETG or ABS for strength. Infill density should be high, preferably above 50%, to withstand the weight of loaded filament. Assembly Instructions Once printed, the holder easily mounts on the top of a shelving rack by sliding the arms over the shelf beams. Ensure it is locked firmly into place to prevent slipping during spool usage.
