I've printed a few of these, and many times the legs end up being extremely brittle at the knees, often breaking one or both legs.
I tried printing them laying flat as well as standing up, and have gotten the knee issue in both cases.
I've also had trouble with the hands/spear connection. Might be my printer/software, but it ends up not building the hands fully, leaving the spear barely hanging on.
I am using a M3D, any suggestions on these issues?
