Saintflint Extruder

This isn't your grandmother's extruder! Kidding... This simple yet very effective extruder is the brainchild of some members from QR's community (in no particular order: Shauki B., Mauro Manco, Dale Dunn, Darkberg Aryavis and myself). I just tried to put it in a neat form. The name comes from the ring that resembles an aureola and uses the flint wheel of a lighter. It was initially designed for a NEMA17 with 1.75mm filament. The nice thing about this design is that it's almost self-locking on the filament, and the forces applied to the stepper motor are cancelled out by each other.
