MYOG Canister Stove Windscreen

I've been wanting to make a windscreen for my canister stove but have been struggling to think of a material to use. I work at a printing company and thought maybe I could use an old plate from the press. The metal is lightweight and pretty easy to cut. I'm happy with how it turned out. Used it this weekend and it worked great. The outside of the metal doesn't warm up at all during use. The whole setup packs perfectly inside my mug.
