Sunlu Reusable 3D Printer Spool Eco-Friendly 1kg Empty Reel for Refill

Upgrade your 3D printing workflow with the SUNLU 3rd Generation Reusable Spool. Tired of throwing away plastic reels or dealing with dusty cardboard spools that jam your AMS? This empty, detachable spool is the professional solution for managing filament refills.

Its optimized dimensions ensure it fits flawlessly in high-speed printers and automated material systems like the Bambu Lab X1-Carbon, P1S, and A1 series. Unlike traditional spools, it features a waterproof, low-friction surface that prevents feeding issues and retraction failures.

Each spool includes a clear parameter label for recording temperatures and a handy weight scale to help you manage your inventory. Whether you are using SUNLU, Bambu Lab, or other major brand refills, this reusable reel is an essential tool for any organized maker space.

• Eco-Friendly & Sustainable: Reduce plastic waste by using refillable filament rolls instead of single-use plastic or cardboard spools.

• Universal Compatibility: Specifically designed to fit standard 1.75mm / 1kg filament refills. It is perfectly sized for Bambu Lab AMS and AMS Lite systems.

• Smart Weight Scale: Built-in graduation markers allow you to track remaining filament at a glance, preventing mid-print runouts.

• Enhanced Drying Design: Features a multi-hole structure that improves airflow and heat conduction when used in a filament dryer (e.g., SUNLU S2/S4).

• Detachable 2-Piece Design: Easy to assemble and disassemble for quick filament swaps using the secure "twist-and-lock" mechanism.

• Cable Tie Slots: Innovative slots allow you to secure unused filament with cable ties before removal, preventing tangles.

• High Durability: Made from high-strength, heat-resistant materials that won't warp in dryers or crack under the tension of high-temp filaments.
