Edit 5/29/17: I added the rotator bar to the wings that will fit this helmet. The problem is the wings will not rotate around the circle on the wings.

Edit 5/15/17: I printed this out at 100% and it was too small for my head. I will print this at 115% and see how it fits. I need a good way of sizing these helmets.
This is the Thor Ragnarok Helmet from the movie Thor: Ragnarok opening November 3, 2017. This was the most accurate I could get it with all the images and stuff out there.
