NYE Ball Drop Gravity Timer

Celebrate your New Years with this Ball Drop Gravity Timer which slowly drops the ball over a period of 30 seconds (give or take 1 or 2 seconds). Most 3D printed clocks require metal rods, bearings, and screws because they need to be precise. However, since this project only really needs to last for 30 seconds, I was able to design a basic timer with no rods, bearings, or screws, you just need a 3d printer.This design is based on a design of a gravity clock. Most people are aware of the standard pendulum grandfather clock which relies on a weight on a string to power it. This design is based on a much older and less reliable version called the Sawtooth Clock or an Anno Clock, instead of using a weight on a string, it uses its own weight to provide it constant power. This is what moves the timer downwards but it requires a rewind much like every gravity clock. Due to the limitations of the sawtooth design coupled with a pendulum, this timer is susceptible to rocking which causes it to b
