I thought of making the Benchoff nickel after I saw Brian’s Hackaday,io profile. He has a hi-res image of the center a Benchoff Buck which is well suited to being converted to a PCB. There is only a few colors and they have sharp edges. Bitmap2Component in Kicad, can easily detect these transitions and convert them into a footprint file. With the help of a text editor, I was able to manually layer everything into one complete image.
The KiCad design files are available on GitHub:
