I've been making some components using glass fibre, finished with car
body filler. They are caps, covers, and adaptors for various sizes of
tube. They will be installed outside so must be durable, waterproof, and
quite tough. The ones I've made are entirely satisfactory except for one
thing: it takes too long to make them. So, I was wondering about 3D
printing. Are the products from these tough, waterproof, and UV resistant?

Ignore TNP he doesn't have one, he just passes on useless info he read
somewhere that he can't remember if you ask him.

They can be if you use the right plastic.

ABS or Nylon would be the obvious choice.
Maybe wood filled PLA and give it a coat of paint/stain.

The tube adapter are probably best made from a flexible filament or PETG
as they don't beak when you bend them like PLA can.

It does depend on exactly how the part is designed as if its really thin
I would print a mould and cast it in glass filled resin for the actual part.
