This small size (about 88 mm high) table lamp would make a good child's nightlight. It can use either a remote controlled LED that can change colors, change brightness, and turn on and off, or a less expensive white only LED light. Both lights require 3 AAA batteries.
For this print I used a seafoam colored filament and a white LED. White or transparent filament works best for the color-changing LED.
Here is a link for the color-changing LED
and this is a link for the white one:
