Laser Cut Kit: Mechanical Clock
This laser cut mechanical clock kit from ROKR not only makes for a fantastic display piece, but is a wonderful functioning model that will give you insight into how clocks worked before the digital era. We wouldn't rely on it as your primary timekeeping piece, but if you get it balanced correctly, it will run for four to five hours on a single wind of the spring.
Recommended ages: 14+
Effort: 4-6 hours
