One of the projects I wanted a CNC router for is to make a rocking chair. So now I'm looking around for a 3d file for a chair seat. I'm sure I can make the outside edge but the 3d part in the center would take some learning. So I started looking around to see if I could find a site that sells files specific to woodworking. Finding flowers and birds seems real easy. I have found lots of guitar shapes. But I've only found one person on etsy. I would think that there would be a market for such things.
