To print, raise the object 5-6mm off the build plate as oriented and generate supports to the bottom and up along the threaded portion. There is a drainage hole leading up from the bottom and into the lightbulb cavity. This hole essential to prevent suctioning during the printing of the bulb and to allow uncured resin to drain out after printing. If desired, it can be filled afterwards with extra resin.
