V-Spooler Filament Runout Sensor and Filament Counter

This is the V-Spooler filament re-spooler designed by

I added a filament counter and a filament runout sensor.

The runout sensor stops the motors and shuts down the cooling fan.

The filament counter is great if you want to make two equal sized rolls of filament.
