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 demonstrate how to upload and modify STEP files into Onshape to suit our specific needs. This rugged box model is very well designed, so it is satisfying to tweak it to fit different objects. I’m going to do just that for some delicate electronics.
