This is the final result.
To create this scanner for iPhone I used:
1 sheet of 10mm FOREX feather or similar material on the size 60x40cm
1 iPhone cover
Step 1: Bridge
I cut the pieces as the attached pdf.
Dashed lines were cut with angles from 45 ° so as to leave a layer of PVC does not cut that will support the next bend.
Step 3: Stand
And here is the scanner iPhone in all its glory to transform in digital any sheet, book or note.
