Short Printrbot extruder gear
by Gecko, published
I made this shortened extruder to match the stepper motor and extruder body which came in the Printrbot+ kit, the one I received was too long and required washers to pack the stepper motor out and position it correctly. When I saw some other people have had the same issue mating issue I thought I should release it here.
Print at 10% infill with no raft or support, use a file to clean the outside edges, insert a M3 nut in the slot, and 8mm M3 bolt in the hole and fit to the Printrbot extruder motor.
