Gear train for 4:1, 12:1 or 36:1 gear reduction
thingiverse
Print out the front plate and back plate first, then select one of the ratio gear trains to print - either 4:1, 12:1, or 36:1. You'll need glue to complete the assembly. This is ideal for automation, robotics, or experimentation purposes. If a greater gear reduction is required, I suggest checking out this worm gear option that offers a 72:1 reduction ratio.
