One could find the part design in a library, and print it at a coop hackerspace or order it online off some pay-per-print shop. It doesn't have to be as complicated as you put it.
But it's a $50 dollar drill, that failed due to a cheap part.
I don't know where you live, but just a diagnosis by a repair technician is more expensive than that. Even if you open it up yourself, find the broken part, find that part someone, get someone to print it,get the part delivered, and replace it, it'll be more than $50 of associated costs... and just because a company wanted to save 50 cents on a plastic gear.
