I've been doing some research on this and wondered if anyone had been down this road before? This double-gear came out of an appliance. The small gear drives a larger one connected to the output. You can see where the teeth were shredded in the center section.
One method of repair suggested coating the damaged threads with a metal-reinforced 24hr epoxy, letting it set up, then using it in place with either wax paper, teflon tape, clear food wrap, etc. to keep the epoxy from sticking to it, to imprint new teeth.
Another cut out the damaged smaller section, slid in a new gear and trimmed it to length.
I spent some time in a hobby shop that carries cars & helo's looking through their selection of gears. No joy. Parts are no longer avail. from the manufacturer either.
Small gear: 11T; dia: 0.38"; Height: 0.37"
Large gear: 40T; dia: 1.225"; Height: 0.13"
Overall H: 0.5"
Tooth height: 0.045"
Any ideas?
