You can learn the whole of Tinkercad in an afternoon and still print parts that do not fit. This book closes that gap.
Most Tinkercad guides stop at dragging shapes onto the workplane. This one starts where those books end: with the rules that decide whether a design survives the printer. You will begin by grouping solids and holes, then move to the ruler and custom workplanes so your models carry real dimensions. From there you build a first complete project from an empty workplane through to a sliced file, learning wall thickness, overhang angle, bridging, orientation, and the clearances that make a pin turn in a hole or a snap fit click.
Written for beginners, makers, students, and teachers new to 3D design, the book pairs clear step-by-step instruction with projects that grow in difficulty. Codeblocks add parametric designs that resize themselves, and the Circuits workspace lets you simulate an Arduino project and print an enclosure to match. Every chapter is built around the workflow of a real print, so you are never learning a tool in isolation from the object it produces.
What you will learn:
• Navigate the Tinkercad workspace and set up an efficient first session
• Combine primitives, holes, and grouping to build complex shapes
• Use the ruler and custom workplanes for precision modelling
• Complete a first project: a printed phone stand from empty workplane to sliced file
• Apply FDM design rules for wall thickness, overhang angle, bridging, and orientation
• Add text, logos, and imported artwork to your models
• Work with shape generators and advanced boolean operations
• Design mechanical fits, moving parts, and snap-fit clearances
• Use Codeblocks for parametric designs and simulate Arduino projects in Circuits
Whether you are a complete beginner, a hobbyist maker, a student, or a teacher looking for a classroom-ready introduction to 3D design and printing, this book gives you the practical foundation to design parts that fit, function, and print successfully.
