Extruder Visualizer Ender 3 S1

Because all the similar visualizer I found are either much to big (hit the fan on extruder head) or need magnet or fall off or are just “to much” I did a fast create of this small and easy version to clip on (5mm axis) the stepper motor only to have simple and effective feedback of the movements. Just function, no deco and overkill ;-)
