KK2 Mounting Brackets for Quadcopter/F450 KK2.1 Case

I really liked a certain KK2 board case, however it wouldn't fit on the quadcopter frame, therefore, I created some mounting brackets for use with the Mini Flame Wheel Style Quadcopter by tosjduenfs and the F450 KK2.1 Case and Mount by rcmanchild.
