wanting to print too large of an object for the 3d printer?

Sure, there are programs that can do that. But wait - you want it for free, right?

Preferably free, who wouldnt? Plus I've seen some very complicated but free scripts for Blender and CAD programs, and the fact that this is such a common thing people will want I wouldn't be surprised if there was something free already.
But if there isnt, I can spend something like $100 if you know of anything like that.

This might be useful

You could give this a try, "Simple OpenSCAD library that cuts objects into interlocking pieces."

Cool. But it looks like it only works on "flat" objects, if you know what I mean. In case I missed soemthign.

No, I don't think this is true. In the download it has some samples. It cuts that Octopus very nicely. I'm Compiling and Rendering a cut version of the Octopus right now.
