Crazy Simple 3D Printed Enclosure with FreeCAD 0.18 Parametric Design Part 3

Like so many of my 3d printing and freecad tutorials, I attempt to solve a real world problem while demonstrating how to use FreeCAD and 3D printers. 3D printing has become the go to method for creating objects which previously required machining. In this series I’ll introduce you to its spreadsheet, equations, and parametric design. As you observe the model, notice the way the internal cavity has been filleted. This is no accident. Instead of converting the model to a mesh, which is the usual method, it’s now quite easy to use the path workbench to generate CNC code for machining. This can be used for such items as machining a rough casting. For embedding in a casting design to facilitate a compartment to contain control electronics in an otherwise hostile environment. Obviously the list goes on from here.
