RGB LED "Mega"star for my upcomming Christmas show :-)
This star contains 146 addressable WS2812B RGB LEDs.
This star will sit on top of our "MegaTree". (christmas tree with about 7100 addressable RGB LEDs in it)
It measures approx. 50 cm in diameter (that's about 20" for my American friends)
Printable on a standard 20cm (8") heatbed.
Pieces can be connected with M4 nuts/bolts.
Here is a small video of the star in action, with the default Adafruit neopixel library test:
connect pieces together with M4 nuts/bolts,
and glue LEDstrips in, so the LEDs face "outward" the sides of the star.
outer ring = 50 LEDs, next ring = 40 LEDs, next ring = 30 LEDs, inner ring = 20 LEDs, inner star = 5 LEDs, inner-hole = 1 LED
(you need to make holes for the wires yourself, depending on how you want to connect the different LEDstrips)
Next, text the LEDs, and glue the middle-top in place.
After this, glue the 5 wing-top pieces in place ...
