Ok, not quite a real atomic clock, not as accurate but so much fun... And you made it :)
I used two filaments to add some contrast and make the "numbers" more readable. It's obviously not necessary but I feel it's so much better.
You can scale this print on the Z axis to accommodate for different size clock mechanism.
If you scale down on the XY axis, you might get in trouble fitting the mechanism through the hole.
