Sherpa mini Extruder Cnc version 3 by Fysetc

CNC Metal Sherpa Mini Extruder V3 – Key Features This latest version addresses TPU filament blockage caused by motor heat in previous models. Now upgraded with high-performance PEEK components, it delivers superior heat isolation and reliability. Now shipping 10 tooth version 3 PEEK (30% glass fiber) gears: Upgraded from POM, offering exceptional temperature resistance, heat insulation, and wear resistance. Added PEEK inserts: Effectively isolates motor heat to prevent clogs and improve performance. Compatibility: Compatible with most FDM 3D printers, including:Voron, CR-10, CR10S, CR-10 4S, CR-10 5S, CR-10 MINI, CR-20, Ender-2, Ender-3, Ender-3 Pro, Ender-3 V2, Gasherbrum K3, and others with custom mounting brackets. Color Options: Space Gray Green Construction: Precision CNC-machined Made from aviation-grade aluminum Detailed Features: Lightweight, hollow all-metal frame for high precision, strength, and minimal inertia. PEEK (30% GF) reduction gears for higher extrusion torque. High-quality nano-coated hard steel gears for durability and smooth operation. Moons’ 36 motor (10T) provides high torque with excellent thermal management. Teflon tube metal fitting included—supports both direct drive and Bowden setups. Spur gears feature mold steel and nano-coating for longer, more stable performance.
