How to expand a 3D box?

Hello
I have a 3D box created in partDesign :

Are there any tools or methods to expand it automatically like this :

or in any other workbench.
I prefer that tool be parametric.

Thanks

Not parametric: mesh and use Unwrap mesh. Or do it the other way round: construct the box in SheetMetal workbench with the appropriate gaps and use the lay flat method.

But don't work. sheetmeta WB works only if the box folded with sheetmetal WB.
In mesh WB I convert my box to mesh with "Tessellate Shape" tool to mesh (with default parameters) and then use "Unwrap mesh" tool but nothing happen.

Indeed; I looked up the documentation and it says why: the mesh has to be unfoldable and needs appropriate seams.
