Description
The MK7 Extruder Drive Gear is a critical component for your extrusion system, engineered to bridge the gap between your NEMA 17 stepper motor and your filament. Despite its compact size, this gear is precision-machined to provide a strong, reliable grip on your 3D printing filament, ensuring it is fed toward the hotend with consistent force. The carefully crafted teeth on the outer diameter ensure maximum traction without damaging, cutting, or scraping the filament during the extrusion process.
Designed specifically for MK7 extruder systems, this gear features an integrated grub screw that secures it tightly to any 5mm motor shaft, preventing slippage even during high-speed or high-torque printing operations. Manufactured from durable stainless steel, it offers exceptional longevity and high operating efficiency, making it an essential replacement or upgrade part for maintaining smooth and consistent extrusion performance.
Key Features
- Precision Machined Teeth: Provides a superior grip on filament, facilitating smooth and consistent extrusion.
- High-Durability Material: Constructed from high-grade stainless steel to ensure a long lifespan and resistance to wear.
- Secure Fitment: Built-in grub screw ensures the gear stays locked firmly onto the NEMA 17 stepper motor shaft.
- Optimized Geometry: Designed to maintain high torque on the filament while preventing grinding or scraping.
Applications
- MK7 Extruder Systems: Specifically engineered as a direct replacement or upgrade for standard MK7 extrusion assemblies.
- Extrusion Maintenance: An ideal spare part for printers suffering from filament slipping or inconsistent extrusion flow.
- DIY Printer Builds: A fundamental component for enthusiasts building custom extruders requiring reliable 5mm shaft compatibility.
Package Includes
- 1 x MK7 Stainless Steel Extrusion Gear
