This is a 3D-Printable Servo clock – or a 3D 7 segment clock. The original project is from Otvinta. It is there you need to download all the 3D files and see instructions on how to assemble the ...

The clock part works as you probably expect — an Elegoo Nano fetches the time from a real-time clock module and displays it on the WS2812B LED strips arranged in 7-segment formations.

By using these driver ICs, the complexity of wiring and control is significantly reduced. “I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano.
