Chamfered primitives for OpenSCAD (Also: Wedges)

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

GitHub repo

What it does

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 still has precedence over this variable

Installation

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

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

OR

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

Usage

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.
