This CNC cut wood is 12mm Beachwood Ply as designed by Eric Beeks who has kindly given permission to use his design to make available to other builders. He is based in the US so maybe best to buy from him if you are too so to save on shipping. The base is cut to the correct diameter to work with the 3d printed slope surround available through the Facebook Dejarick Builders Group. It also adds weight to the bottom to avoid the table being top heavy. The plynth then screws to the base and glues together to help with rigidity which is improved even more so once the plyth is covered in Styrene, thin ply or similar. (The material to cover the plyth is not provided). The top section then screws onto the plyth and is the correct diameter to hold the 3d printed detailed panel. The top section also has cutouts to reduced weight and to make routing of cables into the table far more easier.
