This is a lamp shade designed to work with Ikea's Hemma Cordset. See the instructions for important information about how to print this thing. If you are printing with PLA, then the absolute maximum amount of power lightbulb you can use is around 10-15 watts. This limits you to high-efficiency LED bulbs of around 500-800 lumens. Many CFLs may be too hot! If you are using ABS, then you might be able to get away with 20 watts or higher. I have not tested with ABS, so this is just a conservative guess. Important: Please contact me if you wish to use this (or a direct derivative of this) lamp shade in a commercial environment, or if you are a contractor wanting to use these for residential contract. I won't bite. I swear I'm reasonable.I have successfully printed this object with the following settings:
