Throughout the Pragmatic Metrology video series, the same parts and drawings are used as examples. The 2D prints and 3D CAD models are linked below. I encourage you to download these, print out the drawing and follow along with the videos. Use the 3D models to make your own part by manual/CNC machining or 3D print process.
The videos include practice exercises and demonstrations of how to complete them. You can also find these below. Download and print them so you can follow along with the demonstrations.
