What does this do? CB500 airbox part

'71 CB500

It goes between the plenum and the airbox. Anybody know what it does? Can I just omit, or if I can't find one maybe try and make one?

Interesting.  I just checked my 550 and it doesn't have that piece.  Looks like it might just be a metal spacer that helps strengthen and protect the joint between the plastic air filter housing and plastic plenum.  Probably not absolutely necessary, but I'm sure it serves a good purpose.  Doesn't look like it would be too difficult to fab something up.

I believe that piece is threaded to accept one of the bolts attaching the box to the frame.

As long as it fits and doesn't interfere with normal fitment of the filter box and plenum, I don't see why not.
