It has been mentioned before;

Other than the guy in the link, I don't know if anyone else has tried it out yet.

Does anyone know if the STL file of this is available anywhere? I was talking to a firm about getting one of these made and they said if I can get them the file then they'd have a go at making one for me (they had some interesting strong plastics to try out...) If not then I'll just do it myself. I would want to fill in some of the gaps though (much like Adam Harper did with his mods)
