Not  a very technical conversion   even I could manage it 

I had an old suitcase lying around  and was also looking for a Radio Box ( A vanity case became my battery box earlier : don't ask how I got wife to agree to that )

I also had a few sheets of EPP lying around .
Hence they both added up and became my radio case

Only thing you need for this apart from the suitcase and EPP is a Knife and some thoughtful cutting .

No need for expensive radio carrying cases for me now
