Raspberry PI Zero 1.3 + USB Hub Case

This is a box which can contain a 4 port USB Hub soldered (OTG connection) to a Raspberry Zero (v1.3, but it should works with any others Raspberry Zero).

All details for OTG connection between the USB Hub and the Raspberry Zero can be found here : http://frederickvandenbosch.be/?p=1343

I used a Usb HUB provided by Orange (gift from a french Internet Service Provider), photo here : http://i.imgur.com/FmZyJZ6.jpg
I think various models of USB Hub can be compatible with the box, as long as they are smaller than a raspberry zero (and have 2 usb port on each side).
