this design is still simple, but has a lot more grip than previous design, while returning most of the power to the motor. the other design was off center from washers, and also required a lot of grip force from the motor tension. the new design just forces the filament into side groove gripped by soft nypren, held in place by spring tention to allow for variation in abs or pla thickness.
nice nails!
