The Printrbot Alu Extruder is better than ever! The Alu Extruder v2 is designed to handle PLA and ABS filament as well as improve performance with flexible filaments. The arm of the extruder has been lengthened to give a little more leverage as you load your filament. The machined aluminum parts are easily installed on any Printrbot with an existing Alu Extruder and they are still compatible with the 1.75mm Ubis Hot End.
This will NOT fit on your Dual Extruder Plus.
