Portable wooden CNC machine

Nick Santillan wrote in to share his collapsible wooden 3-axis CNC machine. He decided to make the machine portable because he didn’t have a permanent space to use, and needed to be able to move it easily. Though he certainly isn’t the first to design such a machine, I do really like the fact that it has an open working surface, which allows it to work on pieces that wouldn’t fit in a standard machine. It seems like it could be fun to stick down on top of tables or other furniture and engrave patterns directly into them.
