About this model

Assembly Video: 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. A PDF Assembly guide can be found in the zip file package. Non printable hardware: M2x6 Screw: x9 M3x10 Screw: x6 M3x14-16 screw: x3 Optional: MR63ZZ Bearing (X2) Link Update 10/03/22: Fixed file naming errors and added missing bearing option input gear
