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, I design a more complex part from start to finish to show the complete step by step process. This part is formed by using extrudes, revolves, sweeps and lofts. It is an excellent showcase of the workflow of parametric 3D modelling.
