If you put a minus sign in front of one of the ones in an identity matrix, and
leave everything else alone, it will mirror about the corresponding axis. For
example, this one uses your original geometry, and mirrors the black part around
the X axis. (I deleted the yellow geometry from the file completely):

Notice how I just changed the 1 to -1 for the second use of BlackPart.dat.
