I haven't made the picture, but looking at your picture, you have DGCF at the 10th fret, and EbAbDbGbE♭A♭D♭G♭ at the 11th fret, and all the notes repeat at the 12th fret. So just take the letters from the 10th and 11th frets, copy them down at the bottom, move the fret markers around to match your instrument, and you've got your DGCF fretboard.
