Shelf addition to Lamp pole

This Shelf is printed upside down on the bedplate in Polycarbonate.  It is made to slide down over the upper ½" diameter pole and sit on the lower 1" diameter pole section.  There is a boss on the lower side to install screws with nuts and tighten on the pole.  The PC can likely handle the weight and temperature of most hot coffee cups.  The lamp base must be substantial enough to handle the shelf.  I added a larger wooden base to the lamp to be sure.
