What if you could describe a 3D model in plain, precise instructions and watch it appear exactly as you specified, down to the fraction of a millimeter, every single time you ran it?
And what if the one thing standing between you and that kind of control wasn't talent, but simply never having had a guide that actually explained why the code works the way it does?
OpenSCAD is the most powerful free tool in 3D printing and design, a program where your model isn't drawn, it's written. But most people who try it quit within the first hour, stuck on cryptic Minkowski warnings, invisible subtraction errors, or a wall of code that never quite explains the trigonometry it assumes you already know. This book was built to fix exactly that.
OpenSCAD Guide takes you from your very first cube() to fully parametric, production-ready parts methodically, patiently, and without ever assuming you're a programmer or a mathematician. Every one of its 15 chapters builds directly on the last, and every single figure inside is a real, tested render generated from the exact code printed on the page, not a mockup, not a stock image, not an AI-generated approximation.
What makes this guide different from every other OpenSCAD book on the market:
- A complete, structured path — primitives, transformations, Boolean operations, loops, functions, and modules, taught in an order that actually builds on itself, with five review questions closing every chapter
- The BOSL2 library, covered properly — attachments, rounded shapes, and real, dimensionally accurate hardware (down to genuine threaded screws), a library almost every other OpenSCAD book on the market was written before and simply doesn't mention
- The Manifold rendering engine — what it is, why it can render some models over 40 times faster than the old default, and exactly how to try it yourself
- A dedicated chapter on debugging — the exact console warnings and errors OpenSCAD produces for real mistakes, captured and explained line by line, so a "non-manifold" error stops being a mystery
- Math made calm, not scary — trigonometry and coordinate geometry are introduced gradually, with plain-language explanations built for readers who've never enjoyed math class
- The Customizer panel, demystified — turn your own scripts into slider-and-checkbox tools that anyone can adjust without touching a line of code
- Three complete capstone projects — a compartment organizer, a wall-mount bracket with real mounting hardware, and a customizable keychain tag, each one ready to print
Whether you're a hobbyist who wants to stop fighting your slicer, an engineer who wants parametric precision no mouse-driven CAD program can match, or a maker who's bounced off OpenSCAD once already, this book is built to get you not just using OpenSCAD, but genuinely thinking in it.
Stop copying scripts you don't understand. Start building models you designed.
