A Nautilus-shaped lamp using the Archimedean spiral as inspiration.

Use Bambu PLA Basic - Jade White for the perfect translucency and lamp-shade color. The shade can be printed on its top, for the smoothest finish, but it's a hard print. Slow printing at low temperature and with a glue stick will help get the best finish, otherwise it can be printed in its normal orientation, but will have jagged edges at the top, depending on layer height.

Glue or tape an LED light strip on the inside of the lamp shade shell, looping back 3-4 times, depending on the desired brightness. Start just above halfway down the lamp shade so the LEDs aren't visible when looking at the lamp.

The center of the lamp shade will snap into the center of the base, and the outer shells will rest against the edge of the base.
