There are two .stl files provided. One has a provision for a key ring, the other is just the interlocking gear print which is a great example of what 3D printing makes possible. .
The design has an inner gear, 6 central gears and an outer ring also with teeth so they all have to turn together. Although there is a total of 7 inner 'separate' gears the design will not fall apart. It is a single print and each gear turns in conjunction with the others.
Just another unique fun 3D print that shows the potential this technology offers.
