Tealight Lantern makes a hex lantern for flameless LED tealights — diamond, heart, or star cutouts punched through thin walls that glow warmly when the light is inside. Wall thickness is the magic parameter: the 1.6mm default is thin enough that white or natural PLA glows while staying rigid. Radius sets the footprint — the 30mm default comfortably swallows a standard tealight — and Panel Height stretches the lantern into a taller column of light. It prints standing upright with no supports; the cutouts are shaped to bridge cleanly. Use translucent or light-colored filament, since dark colors block the glow and leave the cutouts doing all the work. LED tealights only — printed plastic and real flames do not mix.
