Hey Zulfe,
I also was thinking about an enclosure before my printer came. My main purpose was to get any plastic fumes out of the house. In practice, I have a small sectioned off laundry room that allows me to seal in the fumes, so I haven't needed to continue work on this.
If this is any help to you I had a thread where I was sharing my design for a 8" Makerfarm i3v.

If you decide to design one, I'd recommend plywood sides, top, and bottom because acrylic is expensive! If you decide to design one definitely share some pics! :D
