So I am trying to build my Chief armor and my 6yr old son an ODST armor at the same time.( what can I say I love a challenge.) Fortunately the print files for my son can be printed mostly in one piece. So it is going pretty smoothly so far and here is the progress after about 2 weeks. And yes I know that is the fire fall helmet from infinite. But I let my son pick out every part for his costume and colors so it would feel like he had a hand in making it.
