Dual Drive Gear Kit

Precision extrusion starts with the right gears. Our Dual Drive Gear Kit is designed to provide the strongest possible grip on your filament, ensuring a smooth and skip-free feeding process.

Standard single-gear extruders often suffer from filament grinding or slipping, especially when printing at high speeds or with flexible materials like TPU. By using a Dual Drive system, both gears engage with the filament, doubling the contact surface and providing a consistent flow rate. This kit is a core component for the My-Cloner and is fully compatible with the EVA Extruder used in our My-CoreXY project.

Why this kit is essential for your DIY Printer:

• Hardened Steel Construction: Built to last, even when printing abrasive filaments like Carbon Fiber or Wood-fill.

• Anti-Grinding Design: The precision-cut teeth profile grips the filament firmly without deforming it.

• Perfect for Flexibles: The dual-gear synchronization is the secret to successful TPU and TPE printing.

• Maintenance-Free: High-quality needle bearings included for long-term, low-friction operation.

Technical Specifications:

• Material: Hardened Steel / Stainless Steel.

• Compatibility: BMG Extruders, Prusa MK3S, and custom Open Source designs.
