About this 3D model

At the NYC Resistor laser cutting class I embedded one of Zach's planetary gears in one of Zach's planetary gears. This design was laser cut from black acrylic and sandwiched between two clear acrylic sheets. I found that the inner circle in the front layer needed a smaller diameter to rotate smoothly. I also cut a gasket that sits between the front and gear layers. Otherwise the gears always contact both the front and back layers. After class I took my project to dinner with a few friends where it was an interesting conversation piece. Someone should turn these gears into something that can be 3-D printed.
