the table is a cad model availabe on Onshape: 3 actually, one from Ryan, one from Jonathan and one from doug ( i didnt read the full context of your message and asumed you were asking for the cnc model not the table )
i went with steel tables, ended up being 1/2 price of mdf/wood
this is really above my pay grade, i use full sheet machines in my shop and they all are in a big room with one vac per machine.
