Here's another Iron Man 3 armor variation for your Armor Vault, the Igor Heavy Lifting Armor. He was created from a Captain America Stark Tek Mech Suit with the forearms reversed and Aves Apoxie Sculpt for the extra armor. Since the suit was hollow I used parts from an Armored Avengers War Machine but any Iron Man armor would probably do. Some Hobby Base Ball Joints were used for the head and torso sections and he was painted up with the scuffed detailing as glimpsed in the movie.
