To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that. In this episode, we explore the concept of variables in CAD. By creating a named value outside of any sketches or features, we can then reference that value and use it to drive geometry. If the design needs changing, only a single variable needs editing rather than going through and editing each feature. Variables offer an efficient way to make your design flexible. 0:00 Introduction 3D design for 3D printing Onshape playlist: Direct link to create a free account: Source CAD for tutorials: 0:38 Variables in CAD and why they are useful Threadless ballscrew by 2n2r5: :124706 OpenSCAD: 2:35 What we are designing/modifying Underhouse workshop video: 3:41 Taking measurements Digital calipers on Amazon : 4:18 Simplified example of variables 6:13 Using simple maths with variables 6:57 Setting draft angle with a variable 8:14 French cleats design using variables 9:50 Printing and testing the final parts Buy quality and affordable filament from X3D.
