Create OpenSCAD primitives with 45° chamfers

Chamfered primitives for OpenSCAD

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

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 stil has precedence over this variable

Changelog v0.3:

• Added a global override for the standard circle quality

Changelog 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

Installation

• Download the library
• Unpack it to OpenSCAD\libraries
• Restart OpenSCAD

OR

• Open your console
• Go to OpenSCAD\libraries
• Run 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.
