HintLightbulb.png 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. However, it is still cabable of basic production, with its Volcano nozzle for large nozzle sizes up to 1.2 mm. 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. Picture here shows Angle Bracket in production:

Note - some duplicate parts are listed below. The four particular parts were used in the simple extruder build in London, Ontario in October, 2019. These have been added here with the hopes that we will somehow organize them better William - October, 2019
