Print with a 0.6mm nozzle or larger with the smaller diameter end down on the buildplate. The voids are designed so you can print as many initial bottom layers as you like for strength (it will be hanging from this surface - I usually do 4 layers) and to accomodate a 40mm thread or plate to hang the shade from. I use the lamp holder posted here https://www.printables.com/model/525049-lamp-holder by @Robby_659862 on quite a few hanging lights around my place where I don't have a threaded pendant socket. Works great!
