This is a hexagonal side table I designed a couple of years ago and cut on a CNC router out of 0.5" plywood. You may need to tweak this to adapt to a different material thickness. The slots in the top surface are 0.35" deep pockets; don't cut them through the table. I went around the underside of the tabletop with a routing bit to give it a nicer edge.

The DXF files are prepared in inches.
