This design work for you? The base needs to be wider of course. Head rises and lowers to adjust for height of doll. Motor shaft rotates with off center belt attachments to make the vibrating action these machine are noted for. Ill be making the belt dynamic so it works with any doll, any shape and can be used in animation. I have no inclination to add in morphs to the belt for specific characters and their morph packs. If you truly require a belt for a specific character and morph pack such as V4 and her Morphs++ then you are on your own. I can add a readme that explains how to use the cloth room but if you are not willing then I'm done here and this will appear at a free site at some time in the near future. What you are asking for is a paid product due to all the work involved adding in morphs for various characters. That or you take the OBJ belt and add in the morphs you need for the characters you have yourself.
