Here it is. Is not the blue thing (on the right) an Up 3D Printer (from Iron Man III)? Pity it is not a RepRap 
When I saw this scene in the movie it really bugged me. Everything seem like it was a kids version or a cheap version of what Tony Stark actually had. If you want a mind to grow you give them real tools, that can do real work, that can create real things. Also, Tony Stark would not have fixed the car, he would have left it to that young man’s own ingenuity and desire.
Potato in Iron man!! Woooou
