Concerned about the constant need to replenish consumables and the potential disruption to your 3D printing projects? Look no further than the Creality Digital Spool Rack - a precision tool that not only precisely measures and displays the remaining filament weight but also enables you to effortlessly compare it with the estimated filament weight required as per your slicing software. Say goodbye to the anxiety of unfinished prints and hello to uninterrupted, seamless 3D printing. Key Features: - Creality original 3D digital Spool Rack specially designed for 3D printers, endows the filament spool rack with an electronic scale function to know the remaining filament weight at any time. It's small and portable and doesn't take up space. Capacity: 2kg, - One-button touch operation, concise interface, simple operation logic. Easy installation and wide adaptability. long-term energy storage, stable performance, standby for 3-6 months with one charge - High-brightness digital tube display, the overall appearance is simple and elegant, intuitive and cool, and the filament weight is easy to read. - Accurately weighing and showing the remaining filament weight, and you can compare it with the needed weight of filament estimated by slicing software , so as to determine whether the remaining filament is enough for model printing, and avoid insufficient filament causing unable to print the complete model - The spool rack has built-in bearings to reduce the feeding resistance of the extruder, making the feeding smoother and reducing roller wear. The large-diameter roller design fits better with the filament spool, reducing the large shaking of the filament and helping the printer run smoothly.
