Note that a flat should be filed onto the stepper shaft as on P14. The flat does not really have to span the whole shaft. It is enough if it at the place where the gear-wheel will sit.
Before filing put some sticky tape around the shaft where it comes out of the housing. Filed away swarf could be dragged into the motor by the magnets and damage it.
