This is my first Xmas tree ball. :-)
It is based on a Wemos D1 mini (ESP8266). 6 LED rings WS2812b are needed:
e.g., RGB LED Ring WS2812 5050 - https://a.aliexpress.com/_EHi4e8B
2x 1bit
2x 8bit
2x 12bit
There are six parts to be printed:
2x HalfBall
2x InnerPart
1x Spacer
1x CenterPart
I used transparent PLA.
The Wemos D1 mini is mounted in the CenterPart. The spacer ensures the position of the Wemos. The two half balls can be screwed onto the CenterPart. No gluing is necessary.
