A library to create primitives with 45° chamfers in OpenSCAD.

The commands chamferCube and chamferCylinder can be used to create chamfered versions of the existing cube and cylinder commands.

The Chamfers are always at a 45° angle to the ground plane and are printable on Fused deposition modelling (FDM) printers in a good quality.

Additionally

• The chamferCylinder can also produce a circular sector (wedge), what the cylinder command cannot
• The circleSegments function calculates the amount of segments needed for a certain circle radius, it reproduces a much better quality than $fa and $fs settings
• A globalCircleQuality variable can be set to globally override the standard setting of 1.0, but the quality setting in chamferCylinder stil has precedence over this variable

First find out where your library folder is by opening OpenSCAD and clicking "File -> Show Library Folder", then do:

• Download the library
• Unpack it to the library folder
• Restart OpenSCAD

OR

• Open your console
• Go to the library folder
• Run git clone https://github.com/SebiTimeWaster/Chamfers-for-OpenSCAD.git
• Restart OpenSCAD

Don't forget to import the library to your script by adding this to the first line:

include <Chamfers-for-OpenSCAD/Chamfer.scad>;

Please read the documentation in Demo.scad to see how to use it.

v1.1:

• Improved preview rendering of cylinders (see Artifact-Test.scad)

v1.0:

• Changed parameters of chamferCube and chamferCylinder to work similar to the original cube and cylinder commands. This is not a breaking change, but please contact me should you encounter compatibility problems.
• Changed license from GPL 3.0 to Creative Commons license to give users more freedom.

v0.4:

• Added separate chamfer parameters for the top and bottom sides of cylinders

v0.3:

• Added a global override for the standard circle quality

v0.2:

• Added new circle quality feature (segment calculator) which introduces an incompatibility with v0.1
• Prevented cylinders with height 0 from being created when setting chamferHeight to 0
