Here is the file (I hope).
I have run DRC it looks good. Of course that is once we ignore the obvious issue that I have routed trace over some of the unused pads under the relays. The pads are left over from the original 16 pin chip that formed the base of the relay layout, hopefully this isn’t a problem.
I don’t consider this to be a "finished" design but it would be good to know if I have made any blunders before I have another go. Also, I still need to change the Molex connectors to something 2.54mm through hole and to give the board a more universal application I may move/remove the 5.08 screw connector (labelled Left - Right) in favour of a traditional 6 pin IO for each relay.
