Not so sure really, I've got one but I only use it with a Space Station seatbox. It's quite wide and long though so the MX300 should fit even with the footplate extended. Now the Shuttle is not exactly the most manoeuvrable trolley on the market, so why not use the Maver wheel kit that is designed for their boxes?
No so sure that was a sensible answer either but at least that wasn't meant to be a comic response
