There is something so wildly cool about having an idea, modeling it, and a few hours later holding a physical instantiation of the thing that previously just existed in your head. Something we software people don't get to experience often enough.

Can you share details about Blender CAD/CAM capabilities? I have a CNC router (carves 3D shapes into wood), and exploring what tools can help with that. I keep hearing about Blender's CAD abilities - I don't know Blender well, so I haven't jumped in there...
