This Sprite extruder gear kit is designed specifically for multiple popular 3D printers, including but not limited to the Ender 3 series and CR series high-end models. Made of all metal material, with a high temperature resistance of over 500 ℃, it easily meets the challenges of high-strength and high-temperature materials. Nano coating technology effectively prevents rust, enhances durability and service life. Innovative integrated shaft design reduces the risk of POM nut detachment without the need for additional assembly, ensuring precise concentricity and smooth rotation, achieving more uniform wire feeding, and making your printed works more delicate and exquisite. Selected high-quality POM and mold steel, CNC precision machining, excellent gear strength, wear resistance, and corrosion resistance, significantly improving load-bearing capacity and service life.
