3D chain mail hood

It always bothered me that there was no good way to take pieces of flat printed chain mail and join them in a way to conform over a 3D surface. Normal fabric can be joined with curved seams so the finished pattern conforms to a 3d surface but chain mail will end up with loose links or bunched links and will just look messy. I have seen 3D printed clothing where they change the size and shape of each link to make the pieces conform but this requires that each piece be custom designed.

So here is a way to do it but it requires that the chain mail have 3-way rotational symmetry so it can be patterned as equilateral triangles. For this project I modified a chain mail I designed earlier: https://www.thingiverse.com/thing:2611564 so it could be printed as equilateral triangles. Joining 6 triangles will just make a flat pattern but joining 5 triangles so they all meet at a point will not lay flat. An icosahedron is made up of 20 triangles all meeting at 5 to a point This hood example
