All Metal Geared LEFT/RIGHT BMG Style Dual Drive Extruder

Description

A BMG style extruder.
Uses an internal 3:1 gearing ratio. All gears are metal.
Use with bowden or direct-drive applications. For direct-drive, there is no need for an additional heatsink. Just attach a 30mm fan to the two available screw holes, and insert your heatbreak directly into the extruder assembly, and tighten with grub screws.
