Inspired by the geometry of an artichoke, this beautiful lamp shade is perfect for the home or business. You can use any standard hanging light cord and a low temp bulb (such as a cfl bulb.) We purchased a standard lamp base with a 12 ft cord from amazon and it screws in the top hole with no issues. 40% infill, high cooling, slow speed. May be tricky on some printers so you may need support for some of the lower fins. Notes: The model was created in 3ds Max 2011 but due to the inch/mm unit issues the model is scaled up by 2540%.
