We don't know anything about the STL file format, though it probably wouldn't
be hard to convert from it to one of geomview's formats, specifically the
OFF format.  That takes a table of vertex positions, and a table of 
faces, listing vertex indices used for each face.
For example, here's a tetrahedron:

OFF			# or "NOFF" if vertex-normal follows each vertex
4 4 6			# Vertices, faces, edges (edge count ignored)

0.0 0.0 2.0			# vertex 0
1.632993 -0.942809 -0.666667	# ...
0.000000 1.885618 -0.666667
-1.632993 -0.942809 -0.666667	# vertex 3

3 1 0 3			# 3 vertices (triangle) on verts 1, 0, 3
3 2 0 1			# etc.
3 3 0 2
3 3 2 1


Geomview might well be a suitable package for viewing your files.  It's not
shareware, but freely redistributable.  It does only run on UNIX systems,
though.  See:
