OpenSCAD Library Creates QR Codes on the Fly

OpenSCAD, a powerful tool for creating 3D models through code. One of the key reasons we frequently use it is its parametric nature, which allows for easy modifications and dynamic object creation. Since OpenSCAD uses code and variables to describe objects, it’s simple to generate multiple variations or cloned objects with just a few lines of code using a for loop.

Recently, we came across a fantastic OpenSCAD library called “scadqr” created by xypwn, which further explores the blend between coding and physical object creation. This library allows users to generate QR codes directly within OpenSCAD with minimal effort. After testing it, we were impressed by how easy it is to use.

The ease of use is remarkable; you only need to include a single file in your OpenSCAD script to start generating QR codes. In fact, it’s even simpler than that—if you’re working in an environment that doesn’t support including external files (like Thingiverse’s Customizer), you can just copy the library’s code directly into your project. No additional libraries or APIs are required; it’s all self-contained in one straightforward file.

There are numerous practical applications for creating QR codes directly within OpenSCAD. One compelling use case is part identification. Instead of relying on simple version numbers, you could embed detailed information into each 3D-printed component, such as the renderer’s name and the rendering date. Alternatively, each printed part in an assembly could have a unique QR code linking to its specific page in online documentation, making it easier to manage and identify parts in complex projects.
