Filament pulley for an Ender 3 with the filament run out sensor and metal extruder feeder drive.

I didn't like the way that the filament would drag as it entered the run out sensor. I wanted a pulley so the filament would enter more centered.

The second issue I wanted to solve was the alignment from the sensor to the upgraded metal extruder feeder drive. I made the pulley with a 2mm base for the sensor to set on to raise the sensor.
