Before ordering, I had some inconsistencies with my flow during printing, so I took apart my extruder and found one of the bearings had gone bad. Ordered this replacement/upgrade extruder and it was instant night and day change. I am now back to the reliable and high quality prints I previously had on my K1. 3 screws, $30 dollars, and now my printer is no longer failing every print. Worth every penny, glad it was shipped and delivered so fast so I could get back to printing! Read more

Please note if you are still using the original nozzle with the short blue tube: This product version is suitable for the new integrated nozzle of K1 series. If your nozzle is the old split nozzle, please keep the front shell of the old extruder and replace it to this extruder, or consider upgrading to the new integrated hotend Read more
