'[EE]: Tiny bevel/miter gears'

I'm after some tiny bevel/miter gears for a right angle gear system.
By tiny i mean 6mm or so OD.
Preferably with a 1.5mm shaft size.

I've scoured the usual places and nobody seems to do anything much smaller than 12mm.
Does anybody have any ideas where I could go to find them?
quantity is up to 200 but I want 4 or so to test with.
load is pretty minimal, plastic would probably do but I'd prefer brass or better.

You can etch thin brass sheet with hobbyist PCB processes.

The sort of thing you might find in model trains or cars

smallparts.com.au have 8mm OD with 3mm shaft. Is that any good?

I am curious how things like tiny gears and other parts are manufactured but so far I have not been able to find an effective Google search argument. Drilling tiny holes included.
I am betting on stamping.

Plastic ones are typically injection molded. Brass gears maybe
fine blanked stamped or sintered for non-flat types.

Many processes can be used. Things like lost-wax castings or special extrusions can create the bulk of a form, other parts can be done with precision CNC machinery. The field of micro-machining is surprisingly big. This is one company's website: http://jmmedical.com/machining.html

I've seen end mills small enough that they can be used to cut a slot lengthwise in a human hair.
