This is a simple dining table consisting out of five pieces of two kinds. Designed to be made out of 30 mm thick plywood on a big router (ShopBot or whatever else with working surface at least 1200*1200 mm). Laminated plywood would work just fine, otherwise finishing is needed.

Cut the countour with 6 mm bit. Assemble the legs inserting one into another, put the desktop on the top. No glue, no scews.
