3D Filament Spool Winder, Electric Spool Rewinder, with Smart Auto Start Stop Function, Neat Uniform Tangle-Free Winding, Universal for 1KG Spools 3D Printer Filament Welding Wire

FEATURES： 1.Smart Auto-Sensing Technology: Automatically starts and stops for perfect, hassle-free winding. 2.Tangle-Free Respooling: Transfers filament quickly and evenly—no more knots or mess. 3.Universal Compatibility: Works with 3D printer filament (PLA, ABS), welding wire, sewing thread, and more. SPECIFICATIONS： Product Name: 3D Filament Winder Material: ABS Capacity: 1kg per spool Packaging Dimensions: 35×35×35cm Weight: 2kg Compatible With: 1.75mm & 4mm filaments/wires (intelligent detection for 1.75mm only) PACKING LIST 1 × Filament Spool Winder NOTE: Intelligent start/stop detection is optimized for 1.75mm filament. For thicker wires, the feed hole can be easily enlarged with a basic hand tool. Due to manual measurement, please allow slight variations. Please ensure you are aware of these before ordering.

• PRECISION AUTO DETECT & HANDS-FREE WINDING: Built with a high-sensitivity filament sensor, this electric winder automatically starts and stops based on material flow, eliminating tangles, overfilling, and wasted filament. Enjoy fully automated, error-free respooling for 3D printing, welding, and textile projects.
• PROGRAMMABLE CONTROLS & FIRMWARE UPGRADABLE: Designed for advanced makers, it lets you adjust winding speed, tension, motor direction, and LED lighting via built-in software.
• WIDE MATERIAL COMPATIBILITY UP TO 4MM: Works seamlessly with 3D printing filaments (PLA, ABS, PETG), solder wire, sewing thread, and other materials up to 4mm in diameter. Note: Smart start/stop detection is optimized for 1.75mm filament; thicker wires can be used by modifying the feed port.
• EFFICIENT, TANGLE-FREE TRANSFER: Quickly and smoothly transfers filament, wire, or thread from large industrial spools to compact, travel-friendly reels. Its precision timing belt and gear drive ensure even, organized winding, saving time and reducing material waste.
• DURABLE, LOW-NOISE BUILD: Featuring a reinforced frame, precision bearings, and a quiet intelligent motor, it operates stably for extended use. For 3D printing labs, workshops, and DIY creators, supporting spools up to 1kg for reliable, professional results.
