This is a housing for the Crazyradio USB dongle (http://wiki.bitcraze.se/projects:crazyradio:index) which is part of the Crazyflie quadrocopter (http://wiki.bitcraze.se/projects:crazyflie:index) kit by Bitcraze (http://www.bitcraze.se/). Just print, drop the PCB into the bottom part (with the little ledge inside for the PCB to sit on) and close the case with the top lid. Version 1.1 adds rounded corners and edges for a better haptic, latching mechanism to hopefully improve long term pressure fit of both halves, some optimized measurements and an optional Bitcraze Logo "etched" into the top.Originally hosted here: http://www.thingiverse.com/thing:84295, now migrated for good
