Matt Denton is a YouTuber who loves Lego. But, as a maker, he's not content with leaving it at that - instead, he 3D prints Lego kits and makes them much bigger. He then assembles them with his nephew, and hilarity ensues.
OpenSCAD is a powerful, free and open source modelling tool that lets you make precise 3D models with just a few lines of code. With the right setup, you can even make adaptable, "parametric" models. In this OpenSCAD tutorial, we'll get acquainted with the software, review a simple example and then discuss how to make parametric designs.
