printrbot JR matched extruder gear set
Description
This Replaces The Stock Extruder Gear Set, Its 10 Degree Helical Cut Gears, 18T Pinion With A Keyed 5Mm Shaft Hole, And 60T Spur Gear, Must Use The Spacer To Get The Filament Alignment Correct, And Prevents The Gear From Hitting The Bottom Screws. His Gears Are 32 Pitch Configuration, They Are Finer Then The Stock Ones, And Might Need To Tweak The Extruder Motor Steps To Compensate, The Spur Fits On The Hobbed Screw Little Tight, Just Little Force It Will Fit, I Did It This Way To Prevent Having Too Much Play
