To help children learn analog time display.
By turning the knob on the back of the clock the hands will move.
Alternative dials and hands are added for a personal touch.
Using the blank dials you could even make your own dial designs.

The parts should be printed on a smooth build plate.

Sliced with PrusaSlicer, 0.2 mm layer height, no supports, no glue.
Downscaling to 80% is tested with success.
