搭配 FreeCAD 與桌上型 3D 印表機的現代工作空間

A modern, clean workspace showing a computer screen with FreeCAD open, displaying a 3D parametric model of a mechanical part. Next to the computer, a small 3D printer is printing a similar object. Include realistic details like tools, sketches, and a notebook with handwritten design notes. The scene should feel bright, approachable, and inspiring, highlighting both digital design and real-world 3D printing in a beginner-friendly environment.
