This 3D Printer upgraded accessory kit is widely compatible with CR 10, Ender 3 series, Wanhao D9, Anet E10, Geeetech A10 and DIY 3D printing machine.
The extruder design with Dual Drive Technology, 3:1 Ratio of extruding with high strength, able to print more kind of 3D printer with good precision. And its transparent shell for a better observation of filament feeding status.
Comes with two stainless steel wheels to grab the filament from both sides, high squeezing force to ensure smooth feeding and quick retraction.
Premium PTFE tubing with the lowest friction on the market. Less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear, and tear on the extruder and less clogging.
2 * PC4-M6 and 2 * PC4-M10 Pneumatic Fitting to secure PTFE in extruder and hot end. The PTFE cutter with an extra sharp blade edge is also included to ensure that the PTFE is cut flat on both sides to prevent any malfunctions or heat creep.
Features: This 3D Printer upgraded accessory kit is widely compatible with CR 10, Ender 3 series, Wanhao D9, Anet E10, Geeetech A10 and DIY 3D printing machine.

Comes with two stainless steel wheels to grab the filament from both sides, high squeezing force to ensure smooth feeding and quick retraction. We have successfully improved the gear and consumable engagement problem, improved the durability and reliability of the gears, reduced the consumption of gears, and extended their service life. Premium PTFE tubing with the lowest friction on the market. Less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear, and tear on the extruder and less clogging,  suitable for thin filaments such as some ABS or Nylon. Useful Tool: 2 * PC4-M6 and 2 * PC4-M10 Pneumatic Fitting to secure PTFE in extruder and hot end. The PTFE cutter with an extra sharp blade edge is also included to ensure that the PTFE is cut flat on both sides to prevent any malfunctions or heat creep.
