The lamp is made to not have to use supports, but if you want to give more quality to the lower finish and not have to sand it later, you can put supports on the base, but be careful, that the supports are never made in the center where is the hole to put the electronics, otherwise it will be impossible to put it in the middle of the print, to do this use the tool Cura de bloqueador de soporte that is in the left bar below and then click on the model to display the square, then enlarge the square of support blocker and center it, I leave image. My advice is to use supports up to the first line of the ball as shown in the image.
I use cura with two different printers, one is the anycubic Mega pro and the other an Artillery Genius Pro, For the printing parameters I use with 0,4mm nozzle for lithophanes I leave the curaprofile files for you to download.
On how to put the electronics I leave images to guide you, I put it in motion so that there are no lines on the ball, but you can do it pausing until you get looseness, watch out that when you put the electronics with the hot silicone you can tilt, so be careful and if it tilts put it back to stand and so until the silicone hardens.
The link to buy the electronics is as follows:
