Filament Puller

I like this design because i dont need some stupid durathane rollers :)
I bought the paint/inkt rollers :)

Because I already bought the Nema17 planetary motor as suggested by lymann http://www.banggood.com/Planetary-Gearbox-Motor-Nema-17-Stepper-Motor-Deceleration-Planet-Reduction-ratio-15_18-p-995316.html?rmmds=myorder , i decided to copy this design and change it to be used with a Nema17
