Simplest Extruder Visualizer

Print in any color or plastic you choose, it's simple after-all. Use one of the spare magnets included with your Prusa printer. Two heights are provided to match the spare magnets, 10mm and 20mm. In the photo, the 10mm is shown.

To assemble, simply press the magnet into the slot and stick the visualizer to the exposed shaft of the extruder motor.
