Found an Oreo or Benchy knob you want to use on your Ender 3 or Ender 3 Pro but it's made for an Ender 3 V2? Look no further than this simple adapter piece. This adapter can be super glued into place, I personally didn't have any on hand so I just tacked it into place with a soldering iron. It should fit snug onto the post of the original control knob.
