Designing a board

This weekend I modelled all the boards etc on solidworks so I could play around with the layout of the components.
I designed a board to mount on top of the dagu tracked base which would enable me to mount everything neatly and route the wires.
I aim to make seperate mounts for the line sensor, ultrasonic sensor etc so I put a pattern of holes at one end of the board to allow things to be switched out.
