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 model our first object: a simple tool holder for allen keys, screwdrivers, etc. The main tools we use in Onshape to achieve this are 2D sketches and extrusion. There is also a focus on construction lines, constraints, dimensioning, prototyping and exporting for printing.
