This is a must-have print head part: for the Original kobra 3/Kobra 3 combo 3d printing project dual gear assembly, directly replaceable original, no for kobra, kobra2 kobra2 neo
Material: Pom And Nano-Coating Die Steel + CNC Process. Reduction gear design, and high transmission ratio, to achieve a greater extrusion torque
One-piece Shaft Design: Ensures better concentricity of gears, reduces eccentric rotation of gears due to assembly, and ensures more uniform 1.75mm filaments delivery by gears
Straight Spur Gear Design: Better engagement performance, smoother gear transmission, more linear power transmission. Large transmission overlap, long meshing time and large contact area make the stress smaller, thus improving the gear’s load-bearing capacity and prolonging the service life of the gear
Lightweight Design: Reduce the weight of the gears by hollowing out the excess material while maintaining the strength of the gears. The Rockwell hardness HRC of the gear as a whole reaches 62-65; the surface hardness HV reaches 1000-1200, which greatly ensures the strength, wear resistance and corrosion resistance of the gear, improves the gear’s load-bearing capacity, and extends the service life of the gear
