Simple case the Adafruit's Bluefruit LE Sniffer. Two different lids are included, one with "BLE Sniffer" lettering and one that's plain. I used 4 2-56 x 1/4" or 3/8" machine screws to hold the case together. The board is a pretty tight fit to keep it from moving around in the case. The status leds, button and switch are all accessible through cutouts in the case.
