Lightweight geared extruder

This is an extruder for a rebuild of an early Prusa Mendel with a 5:1 gear ratio and a NEMA14 stepper motor. The design intent was to reduce the weight of the X carriage without resorting to a Bowden type extruder and to make loading of filament easier than it is in most existing designs.

This extruder has been tested at 60mm/sec with ABS, PLA and Ninjaflex.
