Prusa i3 Millie prints 3DBenchy

I just tuned my extruder, which uses a 50:1 geared direct-drive stepper motor. The motor had been skipping, and I discovered that the gearbox can get sticky if the output post is loose. So I tightened the post inside the gearbox and decided to try 3DBenchy as the first test.
