This is a Novice Mini-Course set out to introduce you to a fundamental "tolerance workflow" in Blender. While building a "Spinner Toy", you'll learn various techniques in designing multi-functional parts for a single design.
We'll be going over more advanced uses of the 3D Print Toolbox. Introducing you to a "Mesh Repair" workflow. You'll also get a crash course in printing with multiple colors with a single extruder.
I'm an optimistic futurist who loves to 3D design for 3D Printing. You are my teacher. I am your teacher. Join me for monthly design challenges at my YouTube channel Print That Thing. I can't wait to see what you create. Share any of your designs with hashtag PrintThatThing and I can find your designs.
