Polycarbonate Light Shade for Overhead Fan

Two 3mf & STL files each included for the Light Shade body and Top.  The body is printed with 1 perimeter using the spiral vase option, but that makes the top too flimsy for supporting the screw pressure when assembling in the Fan base.  So, I made a separate more robust Top piece, cut off the flimsy Top, and then glued the more robust Top in place.  It works fine.  The Shade has 5 spirals to match my 5-bladed fan, if that matters.  I used PC material to resist any heat buildup, and also use CFL bulbs which stay fairly cool.  You can print both pieces and saw off the old top.
