Still worried about running out of consumables and not being able to print a full model? Creality Digital Spool Rack accurately weighs and shows the remaining filament weight, and lets you compare it with the needed weight of filament estimated by slicing software. Highlights: Accurate Weighing Smooth Filament Feeding HD Display Wide Adaptability Accurate Weighing Brings a New Experience Accurately weighing and showing the remaining filament weight, which is easy to compare to the amount of filament needed for the desired model which helps to avoid running out of filament mid printing. Built-in bearing smoother feeding The spool rack has built-in bearings to reduce the feeding resistance of the extruder, making the feeding smoother and reducing roller wear. Large-diameter roller design reduces shaking The large-diameter roller design fits better with the filament spool, reducing the large shaking of the filament and helping the printer run smoothly. High-brightness digital tube display, intuitive and cool It uses a high-brightness digital tube display to display the weight, and overall appearance is simple and elegant, intuitive, and cool, and filament weight is easy to read. Small and portable The 3D Digital Spool Rack is specially designed for 3D printers, which endows the filament spool rack with an electronic scale function to know remaining filament weight at any time. It’s small and portable and doesn’t take up space.
