Simple 3D Printer Extruder

Hint: This is a simple and basic low cost extruder for 1.75 mm filament that can be built from scratch. This is not necessarity optimized for rubber, and will not work with 3 mm filament in its basic form. This is an entry level extruder that can produce reliable prints, but is limited in filament size, will have slower rubber extrusion. Rubber Extruder is a 3mm extruder optimized for rubber, and also optimized for all other filaments.
