Flexible CAD designs using variables - 3D design for 3D printing pt8

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.
