Quicka 2pcs RepRap MK8 Extruder Drive Gear 5mm Bore for 1.75mm/3mm Filament 3d Printer (2Pcs 3.00mm)

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. Specifications: Material = Stainless Steel Outer Diameter = 9mm Height = 11mm Effective diameter = 7mm Shaft/Bore = 5mm
