This tool receives one STL file and split it to several files - one shell a file.

The code originated in Slic3r and the author of the splitting code is Alessandro Ranellucci. It's licensed under the GNU Affero General Public License, version 3.

You'll need the ADMesh libraray, g++ and Premake 4. On Linux, you would use:

premake4 gmake
make

To install stlsplit, put the compiled binary and the shared library into your $PATH:

sudo cp build/stlsplit /usr/local/bin
sudo cp build/libstlsplit.so.1 /usr/local/lib # or lib64

If you intend to build something with stlsplit as a library, you'll also need the header file and .so symlink:

sudo cp stlsplit.h /usr/local/include
sudo ln -s libstlsplit.so.1 /usr/local/lib/libstlsplit.so # or lib64
sudo ldconfig

stlsplit file.stl

As a result, you'll get file.stl.part1.stl, file.stl.part2.stl and so on.
