conjuring music box 3D print model

Parts are sized differently, and no parts are the correct size at all. Attempted to contact the author, and they stated that they lost the files and I should scale them myself. I buy files so I don't have to scale them myself and figure it out. That's sort of the point. So far they look like good models, but having to waste an hour or more to size EACH PART SO THEY MATCH before doing anything is really not something a user should have to do.
