This lamp is similar WiggleLamp3, but has more and wigglier wiggles, and the wiggles have rounded curves instead of sharp edges. The lamp can accommodate either a multi-colored LED light kit or an all-white one. Here are links for both kinds of lights:

I printed WiggleLamp4 with yellow PLA, but it works well with either the white or colored LED. The first photo shows the lamp with the LED off, and the others show how it looks with the LED set to different colors. Here is a short video of the LED changing colors by itself:
