A highly opinionated Inkscape extension to generate living hinge patterns for laser-cut flexures. Several different patterns are available. Select any shape in your document, run the extension, choose the tab corresponding to the pattern you want to use, and apply.

Manual Installation

Create the subdirectory km-living-hinge/ in your Inkscape extensions folder:
- Linux: ~/.config/inkscape/extensions/
- Linux (Flatpak): ~/.var/app/org.inkscape.Inkscape/config/inkscape/extensions/
- Linux (Snap): ~/snap/inkscape/current/.config/inkscape/extensions/
- macOS: ~/Library/Application Support/org.inkscape.Inkscape/config/inkscape/extensions/
- Windows: %APPDATA%\\inkscape\\extensions\\
Copy files from this repo into your km-living-hinge/ directory.
Restart Inkscape. The extension appears under Extensions > Knox Makers > Laser > Living Hinge.
