This is a wearable Arkham Knight helmet.
The original file is from the game rip, then I spent several days fixing and editing the model for print. This was a difficult file to fix.
I've moved the eye holes for better vision.
You'll need to slice it yourself, as well as possibly adjust the scaling for yourself. I've scaled this for me (22" head). If you have large ears, or your head is any bigger that 22", you'll need to size it up. It fits my head like a glove.
My settings: HatchBox Black PLA, 207°C / 50°C
