Special Features

  • Premium Materials for Durability: Crafted from POM and nano-coated die steel with precision CNC machining, ensuring exceptional wear resistance and long-term reliability for 3D printing enthusiasts
  • One-Piece Shaft Design: Eliminates assembly errors with enhanced gear concentricity, reducing eccentric rotation and enabling smoother, more uniform filament feeding for consistent print quality.
  • Superior Filament Grip & Force: Hardened steel helical gear with nano-coating delivers optimal meshing performance, linear power transmission, and reduced stress—HRC hardness 62-65 & HV 1000-1200 for extended lifespan.
  • Upgraded Dual Ball Bearings: Replaces original needle bearings with dual ball bearings, minimizing clearance and boosting extrusion precision to prevent slipping, especially with flexible filaments like TPU/PETG.
  • Exact Fit for ELEGOO Neptune 4 /4 pro: Specifically engineered for the original direct drive extruder hotend of Neptune 4 3D printers; NOT compatible with Neptune 4 Plus, or 4 Max models—verify your printer model before purchase!
