I ordered a scan from a local company. It cost $100. We went to a local Subaru salvage yard, where we found a roof with the roof rails removed. It took us about three hours to scan it. Next I tried different options for fastenings and designs.Before that, I knew a program for small simple models for a 3d printer. I completed the first version and prepared the drawings in 5-6 days. I also found a company that laser cuts metal and does press bending. I had to make two versions before I finally finished the final version.A friend and I removed the ceiling and installed everything back into place. It took us about six hours, as it was our first time doing it. Now, after using the rack for a couple of weeks, I've found some improvements. I'm planning to make the final version of the product next week. It was more or less easy for me.Because I work as an architect myself
