I designed and printed out a little spacship for my little son, it serces as a bedside lamp that can be turned on and off with a little touch switch.

You can also charge the lamp with a normal 1A 5V Charger @USB-C connector.

The Light is also dimmable.

All you need are four 3,3V bright LEDs, B457 Transistor, 20K Potentiometer, 18650 Li-Ion Battery and a ChargerModule, also some wires and a Soleriron and some Solder. And a TouchModule

Here are some links, it is no Commercial and i won't earn money with these links, feel free if you want to build it:
