LED Ambiente Light

I couldn't find such a design on various websites (Cults, Printables, Thingiverse, and Makerworld). So I started Fusion and designed and printed the following lamp. The software runs on an ESP32, which cost about 5€. The print took about 3 hours and 98 cents according to the Slicer. The LEDs are Ws2812b LEDs, which can be controlled individually. The meter with 144 LEDs per meter costs just under 8€. This combination allows me to program
