Managed to get hold of a flight case to replace the cardboard box the unit came in. £38 which is not bad really and a much better solution to protect the OBDStar unit and cables. Having measured the dimensions of the two layer foam packaging first, and checked the internal dimensions of the new case online, I didn't even have to trim the foam down as the whole thing fitted straight into the case. There is a small gap around the edges but it's still a pretty snug fit. Here is the link to the case, for anyone else who has the iScan and wants to ditch the cardboard box. https://www.trifibre.co.uk/product/challenger-tr5023-waterproof-hard-case/
Purchased the OBDStar iScan Ducati unit new from BMDiag. Only the all singing, all dancing MS80 unit comes with the fancy case. The iScan Ducati does not and is supplied in a cardboard box. I bought the protective case new, from the link I posted.
