That one appears to be the up-scaled gearz model. Cannot verify as I have yet to gain access to the downloads. It is hosted at jleslie48.com with no download requirements. Credits in the cover page include ekuth, the builder in the above thread. Nicest one I have seen and appears the textures are photos or scans of same.
I am in the process of removing the fold lines on mine as up-scaling makes them more noticeable.
