Just what I needed to fix my Monoprice Mini Select v2. Direct replacement. Be warned that if you do try to remove the original one, that it is glued to the shaft and you’ll likely strip the head of the set screw. Cover the area with tin foil and heat it up with a butane torch before trying to remove the set screw otherwise you’ll spend more time than necessary to drill out the set screw.Only giving 4 stars because most extruder gears have 2 set screws. I drilled and tapped an extra hole to accept an extra set screw to ensure it’ll stay out rather than gluing it like Monoprice does from factory.
