A display of the star constellations in the northern hemisphere with LED back light.

The model uses a WS2812 LED strip to give the stars a twinkling effect. I used the bare version of the strip and an ESP32 with Wled flashed on it to control the LEDs. But you can also buy the all-in-one strip via the Bambu store linked below.

ATTENTION: Fix the light strip similar to the picture. Do not fix it to the outer wall! This gives the display a more realistic and evenly distributed effect.

Experiment with different light strip positions. If you are satisfied with the effect, fix the strip to the bottom with glue or staples. I also recommend glueing the outer ring to the frame, if everything looks and works ok.

The model in the pictures uses the same color for the text (yellow filament in print profile) and black on the plate called “Stars” in my printing profile. Use a bright color if you want the constellation names to be visible in daylight. For the other two filaments of the “Stars” plate I recommend using normal white or translucent white and black for the best effect.
