leaf table, 20" round glass top, 24" high

rendered in Rhino CAD

legs are 3/4" tubing, rotated ~3.5 degrees so they touch without intersecting

leaves shown as 1/8" thick

leg bottoms match top perimeter (or slightly less?)

legs cross twice, welded where they touch

with a twist!

A slightly more interesting(?) variation is to rotate each leg slightly on two axes instead of just one. This allows the crossing at the top to be in the same direction as the bottom. More complex to draw and build but better? The following are approximate, not precise; designing production jigs is part of the job.
