3D Printing - Buy a Printer or Farm Out?

[Smiler.]

I know a few people on here have them.

I need to prototype some plastic parts but I don't know what's considered "simple".

The image below shows one of them.

The black parts highlight a recess & collar arrangement (approx 1.5mm thick) Overall OD is 41mm, ID is 31mm. length is 75mm.





Are the capabilities of a cheap 3D printer up to the job (£500 budget)? If so, recommendations?

If not, anyone had good experiences with a professional (or amatuer) prototyper?

Thanks for the replies - pretty conclusive which way to go
