r2tincan,
I mounted my hub with four 3/4" x 1/8" rare earth magnets in mounting cups, then another four magnets on the inside of the garment. That was enough to hold it onto my leather coat.
I had a bit of 2mm perspex kicking about, so I cut a bit off and used that to attach the tub lid to the costume, the main body is hollow and removable, very handy space for batteries and inverters. I used some very small nuts and bolts and made sure they stuck out inside the holder (now trimmed) and added a switch for the costume that is hidden when the disc is in place:
