README.md

These are cookie cutters.

My wife drew them on a napkin.

We share them under Creative Commons 3.0 Attribution Sharealike (CC-BY-SA). This means that you are free to do almost anything to and with the data except going commercial with it or reissue them under a different license.

The OpenSCAD files are based on mrbenbrittons excellent cookie cutter script[1] for OpenSCAD which can be found on Thingiverse.

Way of production:

  • photograph drawing on paper

  • Gimp

    • cut down image to work area

    • fix "holes" in the outline with paint brush tool

    • reduce to 1bit depth with appropriate threshold

  • Inkscape

    • import into new Inkscape drawing

    • convert bitmap to outlines

    • switch view mode to outlines

    • use path select tool to cut away outer or inner part of silhouette

    • export as OpenSCAD polygons with Inkscape OpenSCAD extension[2]

  • OpenSCAD

    • create new file from mrbenbrittons cookie cutter[1]

    • include polygon OpenSCAD file and scale to appropriate dimensions

    • render STL from OpenSCAD when satisfied
