The Model is scaled to MY head. You will need to make your own measurements and scale it to yours. I have a big head so you have been warned.
The parts have non manifold edges you will have to right click them and repair them in the slicer.
I'll probably fix them up later but until then just fix them in the slicer.
Print with supports.
I used blender to cut the parts up so it's a little rough but it will work for my purposes.
Update---------------------------
Made helm smaller as it was wayyyyyyyyyyyyyyyyyyyyyyyyyyyy too big. whoops
The author remixed this model.
I just cleaned it up, added some volume and scaled up to fit my head. I have a large head so it may not fit you. I will upload more pictures once it's done printing
