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 a printed part that must match an obscure object perfectly. To achieve this, we use a combination of measurements and a reference photo to generate accurate geometry. We also examine why small print undersized with three potential fixes, and learn how to split parts into two.
