3D Tutorial 18: How to Model a Technical Drawing in Blender 2.81

In this tutorial, you will learn how to model a 3D-printable part based on a technical drawing. Specifically, it focuses on how to couple cylindrical and flat surfaces, and also drill round through holes, without the use of the Boolean modifier.

The tutorial also demonstrates how to test a model for flaws from a 3D-printing point of view.
