I made my own version of this grimdark warrior armor. SebTheis made a better version, and I recommend using his (https://www.thingiverse.com/thing:2913338). Mine is more reminiscent of the boys in gold's dreadnought, so the body parts are still worth using. To connect the wings to the chest, I just used a tiny amount of green stuff to lock it in place and fill the gaps.
