2x 9g servo's (in this case random name "Adeept"). An Arduino Nano, an 18650 holder and a PowerBoost 500C (https://www.adafruit.com/product/1944)
Extremely simple Arduino code here: https://github.com/HonkStonk/Timer-box/blob/main/clockFace.ino
Just added pauses to specific layers to change filament between black/pink to get good contrast.
