Buynew Pack Of 5 MK8 Direct Drive Extruder Hobbed Gear 1.75mm Filament 3D Printer Extruder Pulley 5mm Shaft Reprap

Description

The MK8 is an evolution of the MK7 Drive Gear. The smaller diameter gives 35% more power, and allows for more compact extruder designs. If you need a replacement gear, or you're designing your own custom project, this is the part! Very sharp teeth to dig into the plastic filament for the best grip ever. Direct drive of the filament will give better prints, but you can also use these in a matching bowden-extruder. These gears are designed to work with 1.75mm filament, and do so perfectly.
