This lamp shade was designed to look awesome in every modern interior. At 20cm on all axis it nicely utilizes the whole printing surface of Prusa printers. The model is to be printed upside down on a cylindrical support. This support is a part of the STL model so you don't have to add it yourself. Printing at 0.3mm DRAFT is detailed enough and is the only layerheight tested. A E27 bulb holder and the bulb itself are not a part of the print and need to be purchased/obtained separately.
