This gengar lanterns is approximative 12cm tall when assembled. The hole inside fits an LED candle 18 mm tall and 38.5 mm in diameter. I think it's the common dimension otherwise you can always change the scale for bigger or smaller light!

You are Getting 3 stl :

For putting a light inside
-Gengar bottom side
-Gengar top side

And one in 1 part without hole inside
-Gengar not separated
