CR-10s Pro V1&V2 filament guide for filament sensor

cults3d

I found the initial design interesting, but I added a no bearing wheel and a additional guide so the filament will not detach from the wheel, when the tension is reduced. Also the original sensor bracket is not allowing the filament to be pulled out between the sensor and the extruder, when you have a runout, so I added a short solution with no guide between the sensor and the extruder and a PTFE version, where you can just add a short piece of PTFE tube which can be pulled out, if you have a runout and want to peel out the filament between the extruder and the sensor..
