If you wanted a more durable part, you can send the STL file out to a service that prints it in stainless steel. You might change the design to reduce the bulk because they charge by the gram for the steel.
SpaceX is printing pre-burner parts for their new Raptor engines. If anything needs to be durable it is rocket engine parts. I've read about turbine engine blade retainers being printed in Inconel too. It is not so expensive if you think to reduce the weight of the parts.
