Where can I order a single instance of a metal device?

Question

Electronics

Good day!
In general, there is a desire to make a certain device. There is an electronic component, it remains to make the case. Materials from which it should be made: aluminum, copper. Since this is a prototype, I would like to be able to order only one copy. Any suggestions/ideas?

Answer 1

upd:
@kromobis a hundredth of a mm by 6 mm is one thing, and by 100 mm it is another. What do you mean by 90 degree angle? If you modeled a detail there ala “here 7 degrees, and then a sharp turn” - then I'm afraid your detail may not be technologically advanced at all.
In general, without a detailed drawing, only empty chatter awaits you here. There are many manufacturers, including talented ones. Only now they take an hour of work, they are expensive.
Material aluminum / copper - which ones? Pure aluminum is very difficult to process - it is soft like plasticine. Copper is less workable than brass, for example.
Milling, turning? The only question is the price, there are many manufacturers.

Answer 2

the nearest turner of the nearest factory / scribbles for the production of garage doors / keys, etc.
