Lampshade for an e27 socket that I designed in fusion. The threads for the lampshade are m40x2.5, so you need an e27 socket with m40 threads. I printed it in bambulab black ABS. I'm pretty new to the 3d printer world so I can't really give any better tips on printer settings. I printed with bambulabs setting for abs on a p1s printer. Placed it upside down in the slicer. Got a little fuzz at the top of the print but no major danger. Can probably be achieved better if you go for a lower layer height and a lower print speed. Use a led lamp so it doesn't get too hot and melt the lampshade
Hope you enjoy it
