Intro: Geneva Drive Gear Clock
I designed this geneva drive gear clock a while back but work has prevented me from being able to print it. I have a 3D Printer behind my desk at work but it has been running parts for a couple months now so I can't really use it at the moment. It works by attaching a stepper motor to the orange drive gear. Every minute the stepper motor will take a complete revolution and increment the hundredth place minute gear. After that gear makes a complete revolution, it will increment the tenths place minute gear. After 60 minutes, the hour gear will be incremented.
Step 1: Clock Assembly
Download the stl files to 3D Print all the gears. If you do not have access to a 3D Printer you can use 3D Hubs to find a local printer near you. To assemble the clock you will need a stepper motor, three 1/8" dowels or tension pins(you could also print these), 3 bearings with .5" outer diameter and some rods depending on the bearings you choose.
If you 3d print this, please let me know, as I am very curious to see my design in action.
