Herringbone Gearbox 126:1

I don't know why but i really like to design gearboxes. This one has a ratio of around 126:1 and uses herringbone gears. It works pretty well and can be used for whatever purpose you want( use grease for better performance )

I also included .f3d and .step files so you can easily edit all the parts.

Make sure your 3D prints don't suffer from elephant foot , because that would increase the diameter of gears making them unable to spin correctly.
