The one I created is 70 MB (binary STL). http://www.fileconvoy.com/dfl.php?id=gf0b9d3183adfc0cd10001262478afc1a139ca26919 Carsten Arnholm

Oh, sorry F6 took 75 minutes of course. OpenSCAD doesn't support writing out binary STLs, a simple option many of us are waiting for. -- Sent from: http://forum.openscad.org/

Right, binary STL is a must. Here is some inspiration https://github.com/arnholm/xcsg/blob/master/xcsg/out_triangles.cpp look for "write_stl_binary". You will have to replace things related to carve with equivalent CGAL Carsten Arnholm
