I usually save all the packing boxes for my current machines as they have the most support for them while moving and in case they have to be shipped somewhere for repair. I also have invested in the trolleys and cases for my embroidery arms as I switch out the machines periodically and I use the cases and matching accessory bags to keep all the matching parts with the machine they go with. I also have attacked labels to some of the cabinet inserts to keep them straightened out. I also have a separate storage box for my Bernina feet that would go with more than one of my three Bernina's. I just try and keep the feet that came with or are specific to one machine' with that machine. Who ever thought that keeping all the accessories with what machine they go with would be such a challenge!
