Parts that fit odd shaped objects – 3D design for 3D printing pt4

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.
