Cookie Cutter from Line Art

prusaprinters

The attached SCAD code attempts to take a line art drawing (in the form of an SVG file) and turn it into a two-part cookie cutter (cutter + press). I've tested this out on several images (I use Inkscape's “trace bitmap” feature to create SVG files), and it seems to work well. I only included an image I drew myself (hey, I'm an engineer, not an artist) in order to keep this public domain. The layout() module takes three parameters:width - the width of the resulting cookie (60mm seems about right for a cookie)height - the height of the resulting cookie (you may need to adjust this to the proportions of the original image)file - the path to the SVG imageThe algorithm takes the line art, expands it to a rounded shape around the lines, then creates a cutter around that shape. The lines are then added as raised areas on the press.It should work for most line art. The one instance where it might not is if there's a large empty space in the middle of the image. This could result in a hole in the press, and an extra piece to the cutter.DISCLAIMERPlease adhere to the standard safety guidelines when using 3D printed models around food:Clean thoroughly.Coat in a food-safe sealant.Do not immerse in clostridium botulinum before using.Avoid using within the core of a nuclear reactor.
