Ender 3 Series Filament Guide & Runout Sensor Holder

Filament Sensor Holder for the Ender 3 S1 Series Printers. This innovative upgrade is designed to address the common issue of filament tangles during printing, offering a reliable and efficient solution for seamless 3D printing experiences.

Key Features:

• Swivel Design: The filament sensor holder features a unique swivel mechanism, allowing it to rotate up to 45 degrees on both sides. This flexibility ensures that the filament remains free from tangles and snags mid-print!
• Centering Wheels: Equipped with precision-engineered POM wheels, the upgrade facilitates smooth filament movement from all angles, eliminating friction and ensuring consistent, reliable feeding to the extruder.
• PTFE Tube Fittings: Integrated PTFE tube fittings with PTFE tubes on both sides of the filament sensor ensure that the filament remains centered and free from sharp bends, promoting unhindered movement within the sensor for optimal printing performance.
• Spool Position Control: The addition of a short lever above the holder provides convenient control over the spool position, enhancing stability during filament pulling by the extruder and rotational movements.

Benefits:

• Minimizes Filament Tangles: Prevents filament from tangling around the spool holder arm, reducing the risk of print interruptions and ensuring smoother printing processes.
• Enhanced Filament Guidance: The POM wheels and PTFE tube fittings work in tandem to guide the filament with precision, minimizing resistance and promoting consistent filament flow.
• Improved Stability: The inclusion of the spool position control lever adds an extra layer of stability, contributing to reliable filament feeding and rotation during printing.
