(2) (Left and Right) (Red) Makerbot Replicator 1 & 2 Dual Extruder Upgrade, Thingomatic w/MK7 Extruder - Delrin Plunger Replacement:I had real problems using the delrin plunger system so I purchased a spring loaded extruder upgrade but still had a few problems with not having enough pressure from the spring to keep the plastic against the drive gear (slippage). I redesigned a similar upgrade and use a heavier and stiffer spring then what I originally was using.  I have great results using this now and hope to help a few frustrated comrades! ***This design works perfectly for the Makerbot Replicator 2 and later versions since the arm clears the top end of the stepper motor (see photos). The item kit contains: (2) The Back Plate (left and right) (2) The Swing Arm (left and right) (2) 20mm screw - for the pivot joint of the swing arm (2) 4.75mm OD aluminum bushing - for pivot joint of the swing arm (4) M3 screws (2) New Stainless Steel Ball Bearing (1) Washer per extruder upgrade kit (2 total)   (2) New Compression Spring 30 day guarantee.  If broken, please send back and I will happily replace.
