1. Download the .zip or .tar.gz release file for this library.
2. Unpack it. It should create a BOSL-v1.0 directory with the library files within it.
3. Rename the directory to BOSL.
4. Move the BOSL directory into the apropriate OpenSCAD library directory for your platform:
   • Windows: My Documents\OpenSCAD\libraries\
   • Linux: $HOME/.local/share/OpenSCAD/libraries/
   • Mac OS X: $HOME/Documents/OpenSCAD/libraries/
5. Restart OpenSCAD.

The library files are as follows:

• transforms.scad: The most commonly used transformations, manipulations, and shortcuts are in this file.
• shapes.scad: Common useful shapes and structured objects.
• masks.scad: Shapes that are useful for masking with difference() and intersect().
• threading.scad: Modules to make triangular and trapezoidal threaded rods and nuts.
• paths.scad: Functions and modules to work with arbitrary 3D paths.
• beziers.scad: Functions and modules to work with bezier curves.

• involute_gears.scad: Modules and functions to make involute gears and racks.
• joiners.scad: Modules to make joiner shapes for connecting separately printed objects.
• sliders.scad: Modules for creating simple sliders and rails.
• metric_screws.scad: Functions and modules to make metric screws, nuts, and screwholes.
• linear_bearings.scad: Modules to make mounts for LMxUU style linear bearings.
• nema_steppers.scad: Modules to make mounting holes for NEMA motors.
• phillips_drive.scad: Modules to create Phillips screwdriver tips.
• torx_drive.scad: Functions and Modules to create Torx bit drive holes.
• wiring.scad: Modules to render routed bundles of wires.

• constants.scad: Useful constants for vectors, edges, etc.
• math.scad: Useful helper functions.
• convex_hull.scad: Functions to create 2D and 3D convex hulls.
• quaternions.scad: Functions to work with quaternion rotations.
• triangulation.scad: Functions to triangulate polyhedron() faces that have more than 3 vertices.
• debug.scad: Modules to help debug creation of beziers, polygons()s and polyhedron()s

For purposes of these library files, the following terms apply:

• Left: Towards X-

• Right: Towards X+

• Front/Forward: Towards Y-

• Back/Behind: Towards Y+

• Bottom/Down/Below: Towards Z-

• Top/Up/Above: Towards Z+

• Axis-Negative: Towards the negative end of the axis the object is oriented on. IE: X-, Y-, or Z-.

• Axis-Positive: Towards the positive end of the axis the object is oriented on. IE: X+, Y+, or Z+.
