This lamp is similar to CageLight2 but with the hex grid replaced by a Voronoi cage that has a different overall shape. The Voronoi cage is thicker, easier to print, and less likely to break than the hex grid. This print took 18:41 at a 0.200 mm layer height.
This lamp uses a standard LED "puck" light that can be either battery or wall powered. The base includes a cutout for a wall plug power cord. You can find several types of suitable lights by searching online for "LED puck."
