Summary

After looking for a lantern to print I came across the design from tg92.

Like many others I always buy gadgets I don’t really need, when visiting an "ACTION" store and in this case I bought a LED flame light.
Again, like many others, the first thing I did was taking the light apart and thought I could combine this LED-unit with the lantern design.

After some tinkering the first design was born, version 3 and later on the second design version 4.

Both designs contain a base, a top and a tube to "hide" the LED init.

I printed the tube in white and both housing unit in red, or green, or white also, in any case take the colour you want.

Use support when printing the base and top of both designs, the tube does not need support.

Be careful when you remove the support.

The LED unit is mounted in the base with two wires connected to it, these two wires fit through the opening in the bottom and run through the tunnel in the base.
After fitting the LED unit, you can mount the tube on the bottom and push the top over the tube, it's a tight fit so no glue needed.

Connected the LED unit to a 5V DC power supply (or 3 x 1.5V battery), unit will stay active for 6 hours, then switches off for 18 hours and repeats this cycle until the batteries run out of juice.
