Based on an open-source screw thread library licensed under Creative Commons Attribution-ShareAlike, I'm working with a copy since the original can't be found, making attribution difficult... To secure a lampshade to a lamp fitting, Moertje_220.stl should fit snugly, as it was measured at 20.5mm in diameter; however, both that and 21.5mm are slightly too tight for some printers, which may vary in performance. Print with a material that won't melt or catch fire when in use.
