Eh, they make precision stuff like this all the time. If they wanted to make a bunch they would first standardize the sizing then create production tooling for the grinding setups. Those gears would come out basically perfect every time.

The bigger problem is the output link is supported by the gear meshes. This means whatever load you put on it is directly supported by the small mesh contact patches. A more traditional system can have roller or ball bearing or bushing support.
