OpenSCAD cookie cutter file output
Alexander Pruss
Generate a 3D-printable OpenSCAD cookie cutter file out of an Inkscape document. To use this: 0. Unzip into your Inkscape extensions directory. 1. Convert all objects to paths. 2. Remove all object fill. 3. Make the outer outline be a simple polygon in red. 4. Any inner hollow areas should be bounded by simple polygons in green. 5. Inner lines (which will not go all the way down and hence won't cut the cookie, so they are good for inside detail features) can be black. 6. Connections that connect inner parts to the outside should be filled-in polygons. 7. File Save As... "OpenSCAD Cookie Cutter file" 8. Load into OpenSCAD, adjust parameters, generate STL, print.

This extension adds the option to save to an OpenSCAD or STL file by inflating the filled paths (convert all objects to paths before using) in your object. There are a number of parameters controlling the inflation. The inflation height at a given point x is calculated as proportional to the L^p norm of the exit time of a random walk started at x (with some edge corrections, and with an optional exponential kill-time to flatten tops if desired). There is also included an svg2scad extension that extracts paths to OpenSCAD point lists, ribbons or polygons. It also tries to handle nested holes. The official home of the project is https://github.com/arpruss/inflatemesh
