Prusa MK3 E-Axis Gauge

Just another useless thing to pimp a printer. Shows the movement of the extruder (e-axis) in a psychedelic way. Parts may need some glue between them. You will need an additional magnet of 8 mm diameter. Perhaps you are also interested in my other gauges for the x- and z-axis (2897589 and 2900637). Have fun.
