3:1 Gear Reduction - Stackable

thingiverse

Engineers can build a model that showcases gearing with a precise 3-to-1 ratio on each stage. Multiple stages can be connected as needed, allowing for an almost limitless potential in gear combinations. The model also features a crank handle that can be printed directly into place. The required bearings are 21 OD x 12 ID x 5 wide, and one is needed per frame. These bearings must match the specifications of the 6801-RS type.
