Has anyone ever built the Leanfractal™/ A1-Frac diffuser design?

On this website it mentions that this design is his best. However if you go through the process of giving your email to be sent the download, this design is not listed anywhere in what they give you. The closest that is listed is the Leanfuser™ which is obviously different. Does anyone know where to find the Leanfractal™/ A1-Frac he talks about?
