Vernier indicator for Prusa i3 MK3S
You'll need:
2 filament colors (main and accent)
8x3mm magnet (see notes for different sizes)
superglue
double-sided tape
Printing
print rotor in main color
print base in accent color, add color change to main color to height where the slits start
Assembly
I recommend sending the rotor and base to prevent friction
glue the magnet to the rotor with superglue
stick double-sided tape to the base and cut it to shape
stick the rotor with the magnet through the base and stick it to the extruder (this ensures the base will be aligned with the hole)
Notes
I used 8x3mm magnet - you can use different one, but there are limitations:
small magnets tend to be pulled to the sides and dont stick directly to center
for different height magnets the rotor needs to be modified
the hole in the extruder is 8.1mm so larger magnets won't fit
