Fluted helm 3D model nowhere to be found

I have been searching on and off, for hours at a time and am unable to find a 3D model of the fluted helm / Iron helm.

Others have posted about their wishes for 3D models in the past, to no avail. Here I am trying my luck.

Is anybody able to share the iron helm / fluted helm 3D model with us? OG and/or remake?

PS: The helm makes no sense does it? Looks like you can't open it to get it on. It is enclosed on the neck. Odd.
