I probably have ~40 hrs of CAD time as I kept changing what I wanted to do and how I wanted it to go together.
As for machine time, it's only about 30 min per panel which includes all the ops and changeover in fixturing. The polishing of each panel, anodizing and assembly is a huge amount of time too.
Cost of material? Well, considering I did this at a time when aluminum was the highest, lets just say it was expensive.
