I sure hope that you make VERY, VERY clear to your students that
an STL file translated into ASCII is innapropriate in the real world.
Your exercise could then be of educational value by making the
students familiar with the basic representation of an object in STL
files (triangular facets specified by listing the vertex coordinates
in a specific order) and some of the problems that format encourages.

You could also contact Materialise, and see if they would allow your
class to use an older version under the older terms. Then, you could
put it on the class webpages for your students to download.
