Export object faces

Hi, can I export single faces from a simple object (parallelepiped or cube)?
I’ve tried with the paper model export and is not bad but I need to crop all the faces and the model isn’t straight.
Tried the uv layout export but it export only the base UV and not the images.

AFAIK you can only select you wanted faces, duplicate them, make a new object from them (separate P) and export those.

Thanks, it work.
Selected “mesh > separate > selection” for every face and then exported with paper model one by one.
