Then comes the list of the coordinates of the 12 vertices, one vertex per line.

And finally the list of 8 faces, one per line. Each face line starts with a number indicating how many vertices the face contains, and then lists the indices of those vertices. Notice that six of this object's faces have 4 vertices (these are the sides of the bar), and two of them have 6 vertices (these are the ends).
