Dapol still does the interfrigo wagon kit in 4mm (I think)
It’s H0, sadly.

I received feedback from Sven Hansen, the guy behind the 3d-printed "Haus zu Haus" wagon. He is happy to rescale the wagon to other scales, but as he mentions, the wheel design needs to be considered. He mentioned that he has matching transfers and containers.
You can see more of his products at German insulated ferry van
He is friendly chap and is happy to be addressed in English language. If you want to contact him, the best way is to send him a message through Kontakt
cheers,
