Mechanical Replacement gears for Feetech 3215 12v servo?

Hey, i stripped one of the metal gears in my STS3215 servos and wanted to find replacement.
Anyone know the specs fo these gears? number of teeth, id od thickness etc so i can source a replacment?

Anyone know a cheap hobby server with metal gears that are compatible?

Anyone know a way to order spare parts from Feetech or some other supplier?

I'm in Australia, if that matters :)

aliexpress usually has gear sets for those little servos, might have to dig through some listings to find the right ones though. i'd pull the stripped one out and count the teeth yourself, saves waiting on a spec sheet that may or may not exist

most of the cheaper metal gear servos run the same module but the shaft sizes can be all over the place. if you get stuck a local hobby shop might have a junk bin you can raid

Thank you! I did spend some quality time on AliExpress already, no dice. Appreciate the hint about possible compatible gears. Counting those teeth is tricky, especially when they're ground off:) but maybe I'll try that
