Hi everybody!!
I just want to share with you one of my first 3D designs, which i am very proud of 
It is an ARC Reactor, with an ESP8266 and WS2812B LED inside. I use it to get light notifications from Home Assistant, and also to charge my smartwatch. However, you can use it to much more, since it can work with ESPHome.
If you are interested you can read full guide to make it and use it in aguacatec:
Hope you like it!
