In pepakura halo files 1.7, appears to be only one shoulder, bicep, one thigh, one shin, one forearm, etc. But are they exactly the same on both sides. Do i just print and make 2, or do I need to mirror them? Because noble 6 shoulder looks good one side, but its "backwards" on the other arm (ridges are outward on one arm, but put on other arm, they are inward and can't see them). Why aren't there Left and Right models, instead just one of each???
