VaseMode Light Shade. If im honest i cant remember the exact size but over 250x250x200 is required on your build volume. My printer has 300x300x250 build volume. so bare that in mind. you cant scale down as the light fixture is the size of the hole. if you want a smaller version..... you really should learn to use fusion360 and just make one of these from scratch. it really is just crazy simple. make a profile of the shape you want, and revolve it. boom. lamp shade.
I printed using vasemode. 0.2mm layer, 0.8mm nozzle. The first attempt had gaos in the very top section, I resolved this by slowing down the the print speed to 50% towards the top section.
