How to install BOLTS for OpenSCAD


You can download a stable release or development snapshot of BOLTS for OpenSCAD from the download page. There are different archive types and licenses available, if you do not know which one you want, you should be fine with the GPL 3.0 zip version.

Local installation

Just extract all the files in the archive in a directory. You can now use BOLTS for designs in this folder only. This is a good choice if you want to test development snapshots.

Global installation

To be able to use BOLTS everywhere, you need to install it globally. The best way to do it is to extract all files from the archive into your user library directory. The path for this directory depends on your system:

  • Windows: My Documents\OpenSCAD\libraries
  • Linux: $HOME/.local/share/OpenSCAD/libraries
  • MacOS: $HOME/Documents/OpenSCAD/libraries


To make sure that the installation succeeded, start OpenSCAD, type

include <BOLTS.scad>

and compile. If you installed locally, OpenSCAD needs to be started from the directory, or you can save the two lines into a scad file in the directory.

The preview window should now show a hexagon bolt.
