this would require some exact measurement of where it all fits, but solidworks would help in the design and CNC machining each piece would be good.
CNC machining would be my best option at this point for my design, as it is all flat pieces that are joined together to create the sculpture.
Gossard Workshop in Bld 49
there are a couple of people that are very helpful, kevin would be one man of the the four or so there. what you need, a substantial amount of time just to get everything right to their standards. You will need your file that you drew up tranfer it to Rhino and check over with the staff a few times before making a booking and making your sculpture come to life.
