pic: Sheet Metal Drive Module Idea

Yes -- that's been the thing I've been most worried about when looking at this sort of part. In this case, I've made the center wheel directly driven by the gearbox output and it uses a regular-length hex output, so I think I can get away without supporting it with a bearing pressed into the sheet metal part. So the only things that need to line up will be the two dead axles on each end -- I think they'd be able to tolerate misalignment a little bit nicer than a shaft and bearing would.
