This is a night light designed for LED lighting - I don't recommend using a candle. The sides clip together and just rest on a base with a cover resting on top. The base has a deep cavity to accommodate any LED arrangement and there is an open channel for wiring to the outside, for a bigger battery or mains supply. Without the cover and base, it can be used as a decorative surround for a narrow vase.

I have added a base variant. It is the same size but has ridges all around for decorative purposes only. The channel was printed without support.
I have added two side variants. The holes and tabs are in the same place so the sides could be mixed instead of having each side the same.

Print two copies of each side panel and then clip them together with the tabs in the corresponding holes. The base and cover are not clipped in or stuck, they are intended to be easily removable. It is possible to print the sides and cover of this design absolutely smooth without any evidence of filament build-up. Because the sides are symmetrical, they can be fitted with print bed outwards and the filament lines facing inwards. Since the cover is printed upside down by virtue of the widest pad sitting on the print bed, when this is assembled it also display an absolutely surface.
