Duster Rear Window Louvers

i think im going to give it a shot not sure what materials ill use, but if i can make one good one ill find a a place to make me a bunch for you guys too. i have cad/cam skills but idk a place that would use the file besides sheet metal and that's too heavy. i took a few plastics classes in high school and should be able to bend some the right way using my house stove. ill get on it as soon as i can.
