I just finished the med thighs in pep 3. I separated the right from the left into different files. The left is really just the right, but already flipped for you. I didn't feel like doubling the work.
As with all my latest unfolds, black fold lines = mountain folds, green = valley, gray = flat. I also didn't include one of the rings that was intersecting the model inside that wasn't visible from the outside anyway. Hope that wasn't important. :rolleyes
Iron Man - Med Def - Thigh Left (flipped) - Unfolded by MrOreo123 v2.pdo
Iron Man - Med Def - Thigh Right - Unfolded by MrOreo123 v2.pdo
P.S.
I have no idea for the scale either. I just matched the scaling factor (165.44) for one of the files already released.
