This is for the lifetime plastic 4'x2' tables sold at Costco.  The table height is for about 52 mm or 2 inches.  Cable management is attached to the side of the table.  It is more of a snug fit on the long side of the table than the short side of the table.  I printed at 20% infill.  You will need some flexibility in the print.  I printed several to run smoothly around the tables.  On the long side of the table there are points where this would not fit.  Look under the table to make sure where the cable management clip might fit.  Good luck.
