An extremely unique clock taking design cues from a rubik’s cube (maybe?). From Hans on Prusa Printers:
Time Twister is a fully 3d printed mechanical digital clock.
The digits are produced by twisting the layers to front one of three faces.
Each layer is powered by a micro servo motor.
The servo motors are controlled by an Arduino MEGA.
A DS3231 Real Time Clock makes sure that the time is right.
