#3DPrinting

The two-way to one-way mechanism can be found in most modern automatic watch movements. It is designed in a "flat" or planar configuration to fit the thin movement's case. I've seen other printable designs that use bevel gears, but this planar design makes it much easier to visualize and understand how it works.
