I need a 3D model created of a functional worm gear drive set that ideally can be fitted into a preexisting housing, or will fit with minimal modifications to the housing. I have created a worm gear drive that fits perfectly into the housing, (please see attached image) however despite my best efforts the two gears do not properly mesh. If the gears that I have made can simple be modified to properly mesh, that would be great, but if not new gears will have to be modeled. The ratio between the two gears is not critical, but some ratio similar to the gears I have modeled would be great. Modeling the two gears to fit into the housing is top priority.
