This dual extruder gear kit is designed for Prusa i3 3D printers. The gears come as a set consisting of a primary drive gear with a M3 set screw, fits on a 5mm shaft with a flat side as those on standard Nema17 stepper motors.
Manufactured from hardened steel with a protective surface treatment that will give you long lifetime and extreme reliability. A lithium based grease is recommended to use on the gear section and in side the needle bearings for low friction and to avoid wear. A small dab of grease is enough.
