Inkscape

Updated for Inkscape 1.0

This extension creates cut lines to make a living hinge when laser cutting material. Options include the length of the cuts, the separation between sequential cuts, and the separation between adjacent cuts. All parameters are stored in the "Object Properties" field of the resulting object.

Installation
Download and unzip the file.
Copy living_hinge.inx and living_hinge.py to your extension directory.

--Linux
Run the shell script copy_files.sh. This will copy living_hinge.inx and living_hinge.py to ~/.config/inkscape/extensions
