Danol’s SVG -> Cookie Cutter STL Generator

How it works

• Takes in SVG/DWF files (even in batch)
  • Best to set the SVG to strokes only.
  • It can contain multiple paths.
• Spits out OpenSCAD files
• If you specify OpenSCAD filepath, it can automatically generate STL files
• The OpenSCAD generation is quite slow because it’s using minkowski sum. Well, OpenSCAD sucks :/ But at least I’ve made it when processing multiple svgs.

Settings

Settings can be specified in multiple ways (ordered by priority)

1. File names. File name is split by _ and then every item is scanned against settings list (for example cook1_h=10.svg)
2. Command line arguments to the script.
3. INI file in the directory of the svg.
   • Default ini location: “config.ini” in the working folder.
   • Can set all values from “help”, they must be in the [DEFAULT] section.

Available settings

Usage:
        cookie2stl (options) (files or dirs)
Options:
--baseWidth=4
        (mm) Width of the base
--baseHeight=1
        (mm) Height of the base
--cutterWidth=0.8
        (mm) Width of the cutter extrusion
--cutterHeight=10
        (mm) Height of the cutter extrusioon (including wedge)
--cutterWedgeHeight=3
        (mm) Height of the wedge of the cutter extrusion. The larger this number, the sharper the cutter.
--mesh=0
        If set to 1, a support mesh is generated (needed for multi-path cutters)
--meshDistance=10
        (mm) Distance of mesh grills
--meshWidth=1
        (mm) Width of mesh grills
--meshArea=400
        (mm) Area where the mesh is generated (+-)
--w=0
        (mm) If set to anything else than 0, will resize the drawing so it has weight w
--scaling=1
        (mm) Used for scaling the source svg file. Doesn't make sense combining with 'w'.
--openscadLocation=None
        Location of the scad exe file
--genStl=0
        Will automatically generate STL files if set to 1. openscadLocation needs to be set

Requirements

• Python
• OpenSCAD
