Here's a small Jack-O-Lantern with a removable lid and candle that can be printed with glow in the dark filament!
All pieces can be printed without supports. I used a 0.4mm nozzle and 0.3mm layer height. The wick of the candle is extremely thin and can be broken, so a smaller nozzle or shorter height on that file may help.
