Nokia Lumia 520 Holder

I designed an holder for my Nokia Lumia 520.
I often leave my smartphone on a shelf in the kitchen but I want to know if someone write me without picking it up.
In this way the smartphone become a freestanding object, much more visible and very practical to consult
You can adjust the principal sizes, adepting to your smarphone and to your shelf.
In the front write your name, draw your favorite logo or a pleasant text.
