Question Transport bag for m-uno

Hi everyone,
I bought a m-uno a month ago and am very happy with the first results.

Unfortunately I live in the city so I don't have a fixed location.
After adjusting the latitude and mounting the losmandy clamp the m-uno no longer fits in its box.
With its handle it is comfortable to carry, but needs protection to carry it in the car, and to be stored.

Do you have any suggestions on a carrying case?
I've seen someone use a polypropylene case (www.cloudynights.com/topic/604224-avalon-m-uno/#entry8321592), nice but big and it's 10kg extra.

Does anyone have any suggestions, links, pictures?

Thanks,
Mauro.
