Reference pictures were taken and used as canvases in CAD to get a sense of the shape and difficult curves. A ruler was included in the pictures so that I could extrapolate any unusual dimensions. I also made sure to use the lens with the longest focal length to ensure perspective wasn’t distorting the measurements on the ruler.

After the basic shape was initialized, I grabbed a set of callipers and began precisely measuring all the critical dimensions, slowly constraining the model.
