A client came to me wanting to duplicate a cap for the wheels on his show car. He originally wanted to have the piece scanned and printed, but scanning was not the best option due to the black color and glossiness of the original part. Instead I took some careful measurements of the original cap, and re-drew it in Rhino. After printing an initial test piece and giving it to him to test the fit, he confirmed that it was a perfect fit on the first try! The images below show a wireframe view of my Rhino model (top), and a comparison photo of the printed duplicate next to the original piece (bottom).
