I put together an initial draft to answer these questions for my own wife, and then crowdsourced the rest. So many of my tech friends suggested stuff I hadn't thought of and I'm sure there's more.

The DIYLILCNC is a fully functional, open source 3-axis CNC that you can build with basic tools and parts that can be locally sourced. The idea is that you develop a 3D design in a CAD application, put feedstock into the CNC, and print your design to it, and it cuts and grinds away everything but what your design is supposed to be. Total cost of construction is about $700us. You can download the plans and DXF template files from the website for free (they have a CC-BY-SA license).
