Literally every 3D printing channel is making functional parts out of plastic without asking why the original engineering avoided plastic.

It's like modern cars made with plastic engine components. They are used because they will fail with a set number of heat cycles that just carries the motor (all German makers now do this) just past warranty.

Even Ford is now using plastic oil pans in heavy duty (LOL) trucks.

DIY mechanics think because it looks like a thing, it works like that thing.

This part could have been printed in PEEK but it would have been more $ than fiberglass.
