I would expect that no one is helping, because the information provided is insufficient to create the model. The images I've seen show a planetary gear set in which there is a supplemental part driven by the gear set that spins. It looks somewhat like a flag or pointer on a shaft spun by the gearset. It does not look like a single-tooth gear, which is an engineering impossibility. The closest mechanical system I can imagine is the escapement mechanism of a clock, but that is a two tooth structure and is not a rotating system.
