Description:The improved MK8 extruder has a filament guide tube, all screws, spare drive gear and upgraded Bowden pipe connector for cr-10 3D printers. Our design provides full support for the elastic parts from the inlet and outlet. We have reduced the price and complexity of flexible printing. It also makes printing faster, longer, and risk-free. Frankly, it looks great and performs better than the plastic version included in the stock printer. It allows you to print elastic materials and regular plastic filaments.Features:1. 100% new and in good condition.2.
