Through popular request by Reddit, this is the clock I built and designed from scratch. The original plan was to use a stepper motor and have it controlled by Alexa, (So you could say, "Hey Alexa, change the time to GMT" or so on), but I ran out of time and don't think I'll be finishing any time soon as I have other more important things to work on!
I have to find my Arduino source code for the stepper motor drive, but it's not rocket science if you want to work on it. (Your center wheel is the key here. Your drive gear is exactly half the teeth of the seconds hand. So set your stepper motor to spin twice in 1 minute, you have seconds. While programming in time setting will need some work.)
I have printed the clock, it works just fine. However, here are a few notes/fixes that I think would be good to do.
1. The supports for the middle gears like to come out, as they are not fastened down. I would make a cap with a screw in both towers.
2. Size issues. I made all surface
