Other models can be designed by yourself according to the size and mounting holes. With this all metal extruder, you can have more choices of consumables when using 3D printers. Also, the larger extrusion wheels increase the grip of the consumables and reduce slippage, and the larger ratio increases torsion to increase the extruder's thrust. The extrusion gear is post treated with a hardening and nickel plating process for wear resistance and good printing results.
