It's certainly a cool material. I've considered using it in many places that teams use sheet metal now, since you can get it thicker for the same weight and it deflects under load (elasticity). If you need it to be more solid you just add a flange.
I've been meaning to CAD a polycarbonate drivetrain lately. You might see it in a few days.
