There are no plans to release the files. I checked Shapeways and just the cab alone was close to $800 and that was just a stripped down version that wouldn't mount to anything.
Smart man. Releasing your files is simply stupid. Even if you release them to be free there are always scoundrels that will sell the files and or prints.
Anyway, this build is awesome! The photos in the sand are just amazing. So scale! The video is even better. It jumps and lands like the 1:1 trucks. "thumbsup"
