Sgraber Frame for 9mm

Just edit che Sgraber Prusa i3 design for a 9mm thickness.
That's because I have the opportunity to use 9mm MDF,
I haven't try it yet.
If someone cut this structure before me plz comment ;)

Update:
I have cut both of them ;)
in the photo you can see the structure for the normal and mini frame :D
