Ngôi sao Giáng sinh (Christmas star)

You need transparent filament (PLA)

1  LED (5mm)

2  button cell(AG3/392/LR41)

glue to glue the printed parts together

parts  1x: 

case_01

case_02

loop

washer/part of an elastic band

center

and:

8x: face_3

17x face_4

you don't need any support, I use 0.2mm layer high.

Print the loop seperate so that you get a smooth thread!

Check the printet(face) parts that they match in the center, maybe you have to clean it.

On one of the fotos you can see how the illumination part get together; you don't need any glue for this part.

The rotary switch is very simple, so use it carefully.

The loop with the LED is only plugged in, the other parts are glued in.

Instead of the washer, you could use a elastic band; it works like a spring.
