This does not fit snug for the quest 3 controllers. The fitting was formed to the quest 2 controllers with the round sensor in mind and leaves that part open and not snug with the quest 3 controllers. There is a lot of wiggle and it does not stay in place. Although it does fit due to the similar controller design, I wouldnt recommend it for the quest 3 and would prefer if helloreal remade the handle specifically for the quest 3 controllers.
