If you need to use a lamp longer than the lampshade, you can use a lampshade attachment. Also, perforation with polygons in the form of honeycombs, with a thinner layer of printing, allows you to diversify the appearance of the lamp. Good results are achieved by printing with carbon-filled plastic.
