I have an ultra cheap 3D printer. It does ok, even though it needs some adjustment as things have gotten loose with use. Anyway, I printed an object that I am going to use in a project of mine. The part is threaded 7/8X14NF and has a narrow 1.6mm slot adjacent to a 1/4-inch hole.
The part printed with my One-Up 3D printer is usable, if not pretty. Since it was usable I could have stopped there, but I wondered how it would look if it were professionally printed. So, I had two services print me units. The two services were 3dHubs and Shapeways. The commercial pricing, including shipping, was around $6 per item, from both suppliers.

The simplest thing to do is watch my short video (link below) – you can visually compare the results. Oh, by the way, ALL three prints were usable but one is more professional than the other two.
