Starwasher extruder

Update:
Added files for 3mm filament

Made a slot in the rotating piece which greatly improves filament feed

Made an adjuster using a 3mm screw and a small washer in the slot to keep the filament forced against the o-ring and in between the washers.

Note: There are two sides to the star washers, a "sharp" side and a "smoother" side, make sure the smooth side of both washers is facing the filament if not it will chew it up and make it bind in the tube, it should come out of the feeder with no damage just some small dimples.

When the hot end is at temperature turn the extruder motor "off" , turn the knob and it should extrude plastic out with very little resistance, if it is hard to turn there is a problem somewhere in the hot end.

more modification in the works.
