Prusa i3 Extruder Motor Indicator

The extruder motor movement indicator is a nice and useful addition to the Prusa style 3D printer.
As I have several Prusa models it would be nice to show the model with an indicator.

Thanks to Petclaud for this great design!

For assembly just super-glue an 8x3 mm (diameter x height) strong magnet to the center of the raised part. Let it dry and put it in the extruder motor back rotor hole.
It will follow the motor and indicate the filament movement.

Shown models (old) is printed in 3DE Flame Orange PETG.
