Great item but the shipping box arrived cracked with a large breach on one side .So all the screws and some parts came out from the box even they were supposed to be in small bags . These cracked as well . Fortunately the box was wrapped with a kind of black plastic bag and kept the parts and nothing seems missing by pure chance . Next time send a more solid box . Thank You

Unfortunately the quality is not good as aspected. I found two major issues. First, are to small pulleys. Due to this you need to extend the diameter otherwise the tracks will hit the spacer between the two roll parts. Second, the main body is way out of tolerance. This causes different hight and length of the motor and pulley as you can see in the pictures. Also affected is the tension of the track. One side is more less than the other side. All in all...good parts are only 25 bucks worth and for the rest you need many time for measurement, design and print new parts
