Take the second file attachments

I updated the file  to nothing understand ;-(

I don't understand why it screwed up the first one ;-(

PS:

to be able to unfold with a change of plane

Avoid curves,  the best thing is not to use arcs of circles

but straight lines that at each junction will create bend lines like on a folding machine

make as many lines on the 2 fields even if they are not the same sides
