First Order Helmet Aerator

People were asking for a 3D model of the aerator on the First Order Stormtrooper helmet, so I made one. Thanks to user DizzyStrmtroopr on TheRPF.com for the very helpful measurements and diagram. I needed to make some small adjustments but overall I think this does the trick!

I will update the model if anyone can give me more accurate reference images.

I have not yet printed this myself, but it's simple enough that you should be able to figure it out ;)
