What Can I Print With for This Project

Hello everyone, I've been asked to create something for a friend and I have concerns what filament to make it with. The project is to print replacement fins for water pressured 2-liter bottle rockets.
I know there's a difference between toy plastic and the rigidness of PLA or PETG. Would flex work in this case or is it too flexible

The last thing I would want is for sharp corner fins to come down and hurt a child. Is there a solution or should I back off?

I have thought to round all edges, but there's still potential for injury. And no they don't use or always use a parachute. Mostly a streamer that sometimes doesn't deploy.
