Ordered printed parts from Ebay. This is my first experience holding a printed part and I have to say that I'm disappointed. This the first time I've held a printed part in my hand so I'm trying to reserve judgement but these things look really rough. In fact all of the upper corner supports all have at least one crack along the 'grain' of the plastic. Another wrinkle is that I received what appear to be pulleys instead of gears for the stepper motors. I guess this is a belt drive option but I was not expecting this. Also, the teeth in the pulleys don't seem very well defined. Seems like they would slip easily. I'm including a few pictures. Any advice would be welcome:
