Hall Effect Filament Sensor

Remixed a model of a E3D Titan extruder to build a Hall effect Filament Sensor. Two spherical magnets pressed into the filament guide wheel are detected by the 49E hall effect sensor. I used an arduino and a small OLED display to count pulses.

Hall effect sensor can be found here:

The magnets are 2mm sphere magnets.
