About this 3D model

My first pcb with eagle. Board is not tested (may do so later when I have access to prototyping equipment). A very compact arduino with robotics and wireless communication in mind. Designed to be used with servos, HopeRF TR-HM transceiver, and DFRobot motor driver. Two voltage regulators on board (second one dedicated to servos and powered when VR2 jumper is connected).
