I've spent a decent amount of time trying to hunt this down in the scaling FAQ sections, but couldn't seem to find it. On a Mark VI FLYING SQUIRL chest plate, is the largest measurement side to side from shoulder joint to shoulder joint, or up and down from mid-abdomen to a couple inches above the shoulder? People seem to measure from shoulder to shoulder, but the longest measurement to me looks like it's up and down, simply because of the added inches from where the back and front connect. Thanks and sorry, I just want to make sure before I print and pep out the whole thing.
