Most 3D printed lamps end up looking pretty similar because a lot of them use pendant light kits and are limited in design by the diameter of the socket. I recently discovered these pendant light kits can be disassembled and reassembled allowing for a much broader range of designs that look like traditional lamps.

Note that you MUST only use LED bulbs (9 watts max) as traditional bulbs can get pretty hot and could cause damage to the plastic. I like multi color smart bulbs that I can control with my phone, but any standard 9W LED bulb will do.
