CR-10s Filament Sensor

I designed this to be used with a PC4-M10 PTFE Push in Quick fitting to accommodate a boden tube. This fitting is not necessary if you want to use this a standard spool dispenser for you filament spools. Be aware that I am still working on this. The filament can tend to get blocked when trying to feed it through although I don't have too much trouble with it. Cut the end of your filament at a 45 degree angle to help feed it through. When mounting this it is quite difficult to align the bolt hole
