An STL file containing 15 fobs was generated by OpenSCAD. I want to split
them into 3 STL files each containing 5 fobs.

+++++++++++++++++
//difference() {
intersection() {
import(filename,convexity=10);
#translate([-10,y,-2]) cube([sx,sy,sz]);
}
+++++++++++++++++

However, preview was ok but rendering failed:
http://forum.openscad.org/file/n17446/20160528_17.jpg

The STL and OpenSCAD files are archived here http://bit.ly/1sTZWVx .

Any suggestions?
Thanks

There are endless reports of problems similar to this. Sometimes you can
work around it using MeshLab or other tools, quite often you can not.

For some explanations and opinions around why this is a recurring
problem, see for example this thread:

In Meshlab it shows lots of self intersecting faces - the pink bits, (tho
not many when you let it unify duplicate faces)

You say OpenSCAD generated that STL? Can you share that?

Thanks all for the inputs.

I am not being careful when I say the 15 fobs stl file is generated by
OpenSCAD. It is actually based on an original single-fob STL file given to
me (I think it might have been generated by Pro-Engineer as I was told). I
used openscad to produce fifteen copies with different names engraved.

I thought the 15-fob STL file from the OpenSCAD should be "clean" and I
should be able to do anything with it. Perhaps the original single-fob STL
file was not "clean" and I was lucky to produce the 15-fob STL file. And
when I tried to manipulate the 15-fob STL file with OpenSCAD, I am not
allowed.

I have attached a link to a zip file which contains the original single-fob
STL file "leecostl(final).stl" and the openscad file that could create a
similar 15-fob stl file.
