Another iteration of the Open Box which is the hinged lid variant of the Adafruit Pi Box. This time with a slot and mounting holes for the Raspberry Pi Camera. The holes on the camera fit an M2 bolt.
This and others like it are available at http://www.phenoptix.com/products/openbox-raspberry-pi-model-b-with-camera-mount
Two small (or one large possibly) washers are advised to clamp the camera down to the top plate. We supply them with our kit because it's nice to have them.
