- the clock is 3d printed and uses a cheap quartz movement that takes a double-a battery
- it is capable of tracking the day of the week as well as the month and date, even adjusting for leap years
- version two has slight improvements in terms of aesthetics and usability when compared to the original design
- the only requirement is that the length of the hour axis needs to be at least 12mm long
