A few more parts printed. So far there have been a couple press-fits that are a bit loose. I've updated the CAD models to make them tighter, but in the meantime I can make do on the prototype with loose friction fits. A little thread-locker glue will take care of it. 

So far I'm really liking the new yaw shaft. It is MUCH more stable than the old design and moves very smoothly. The next print will have the motor mount so I can test the gear. But the gear seems to fit excellent when hand fit.
