This is designed to print in two parts, to hopefully minimize clean-up and make it easier to fit on a print bed. It also has screw holes, rather than modeled screws - I actually modeled some on, but based on past experiences it's pretty easy to get hardware and just attach it with stuff like this. These holes are sized for M4 screws.Separates into two parts for printing, with holes for alignment pins (1.5mm diameter, I use brass rod from a hobby store) to make attaching the parts together easier.
This was scaled against a pilot model I exported from Titanfall and set to 6'2" tall, so I have a good feeling I got the dimensions right. Until I have had a chance to print it, though, it's going to be marked as a W.I.P.
The shoulder pads are not identical, and are not shaped exactly the same. The pilot's left shoulder wraps around some sort of padded armor, so it is not as curved on the back. Right shoulder also has a bit more of a taper towards the bottom. There also seems to be a dent or other impact mark on the right shoulder pad, which I modeled into the part itself.
