I need two tiny gears

[curious aardvark]

got a millimetre scale - I don't do inches :-)

And you'll need someone with a resin based sla type printer.

They will be able to make the gears - but I don't know how strong they will be.

Okay after guesstimateing it at about 5/16 of an inch it's around 8mm in real numbers.

I actually just see wheels, no gears. 8mm wheels - no problem.

8mm gears with many teeth - you will need sla machine.
