I placed mine in this thing, but it requires a 3D printer. :)
Cool enclosure. I don't suppose you have a spare? :)
I would definitely buy one of those... no 3d printer :-(
Yep, I found a nice little enclosure at Radio Shack/Circuit City. It's about twice as big as it needed to be, but that's fine. I mounted the board by drilling a hole in the side for the antenna coupling. There is a nut and washer included to clamp it down. I attached a USB cable which is basically permanent. I glued it into the case, so that it doesn't strain the Xbee socket. The wire exits a second hole. So now I have a little black box with an antenna sticking out one end, and a USB connector coming out the other side.
