41.8mm diameter of hole for the 40mm socket to go through and then you tighten on the fastener for the socket and screw in your bulb through the 100mm hole on the top.
I will print on my 0.8mm nozzle Cr10 using white PLA at 0.2mm layer height and 33% concentric infill, one wall, and an alternating wall setting in Cura is applied, it should use 240g of filament. Should be printable without supports, just keep an eye on layer height and overhangs it creates.
