One 8 Kohm resistor (oversized to reduce amount of light emitted by the LED. If LED brights too much, it is not possible to see the stars)

One red LED (any 20mA red LED with 5mm diameter is valid for the design).

Supports are only required for screw holes. Screws used are M2.5.

This design has been printed with one Creality CR6-SE
