Created the SVG file in Inkscape. Converted to .nc file using Easel. Added a lead-out to the gcode by using a regex in Atom (code editor). Cut the pattern into 3/4" plywood using the Maslow. Cut the circle using a router on a jig. Painted the inside of each cutout with epoxy resin to make a seal. Filled the cutouts with colored epoxy resin using condiment dispensers. Added some edge banding to hide the plywood edge. Sanded smooth, and put three layers of varnish on.
