I made my own as well from a scrap piece of .25" aluminum. Picture is before painting. After seeing it my wife said I should have just bought one. Guess she wasn't impressed with my machining skills.
I made some aluminum spacers to fit it above the fender of the type that are supplied with the purchased aluminum racks.
FWIW in case it helps someone, I posted a question several pages ago asking about the mounting hole pattern spacing. The front-back spacing is 70mm and the side-side spacing is 50mm.
