Simple Gear indicator

Unfortunately, my Hamster Wheel https://www.printables.com/model/1840-Hamsterwheel%20extruder%20indicator was not eligible for this indicator contest, so I just created something else: a Lego 24-tooth Technic gear, as they are around since 45 years :-) (and yes, I still have some of them from 1977…)

Print it in light grey, change color at the right height to black, stick a magnet to the back and you'll have yourself a nice looking indicator.

Maybe I'll start making some other Lego-looking parts for my Prusa MK3 to go with it…
