I agree, if you can buy the gear for short money, do that. I have printed gears [~0.5" dia] and racks in high performance resins and they don't come out very well, went back to commercial items-this is for a real product so we need it to be robust.

Regarding the headlight washers, seems feasible, need a donor to measure, etc. There must be internal features that add to the cost? I printed a Carrera badge for a ducktail using a nylon from Markforged. It has been on the car for a few years with no trouble. Light duty, I don't leave it out in direct sun too much. This nylon material has relatively coarse layers, about 0.004" so it will appear rough. The badge is printed so the layers are on the edges, the flat outer surface looks nice since it is a single layer.
