Speaker Box Design / Nautilus Shell

a while ago i drew this up in cad , it took a huge amount of time , 
its a speaker box in the shape of a nautilus shell ,

i played around with the design abit and was going to CNC 18mm MDF sheets , and restack the sheets back together with glue to form a nautilus shaped void in a solid rectangle block 

the cad files are of the " external " shape , where the nautilus shape is seen from the out side
