QR code to OpenSCAD converter

qr2scad - Convert QR code images to OpenSCAD <http://github.com/l0b0/qr2scad>

Default syntax:

qr2scad < input_file

Description:

For each black pixel in the input, it will create a cube in the output.

The result can be used in an existing OpenSCAD file as follows: 1. Remove the QR code from a flat surface using the difference() function. 2. After printing, splash some removable paint or ink on the QR code holes. 3. Remove the residue around the holes with a piece of cloth, leaving the color in the holes intact.

This code does not optimize the output in any way. If you get a really big result file, try to scale it down and verify that it is still readable using <http://zxing.org/w/decode.jspx>.

Installation / upgrade:

sudo easy_install -U qr2scad

Examples:

qr2scad < example.png > example.scad

Convert example.png to example.scad
