I'm still printing mine. But have experienced some problems. I use PLA and I'm not able to seperate the two parts of the forelimbs. They break into two pieces. I use Cura and tried many settings. Even a layer height of 0.2 and 10mm/s as a value in every speed setting didn't work. I also tried many different values for the hotend.
Also putting the body parts together was very nasty. I had to cut a little bit from the round things and apply force to get them into the other end.
