Human: These three-dimensional printed components are used to construct a driving wheel with a quarter-inch diameter rotating one-inch long pin. The large wheel measures two and fifteen hundredths inches in diameter and is one-quarter inch thick. The two and fifteen hundredths inch wheel features a half-inch diameter hole where a small bearing can be placed, allowing for smooth rotation. A quarter-inch diameter central shaft can also be connected to the center of this wheel. The rotating pin has a quarter-inch diameter and serves as the driving mechanism for the wheel. This mechanism can be used inside a Scotch Yoke notch, where it will roll around on the bearing, minimizing frictional forces as it drives the Scotch Yoke mechanism. The distance from the center of the rotating pin to the center of the central drive shaft is three-quarters of an inch. These components were designed using the freeware version of the EMachineShop software, showcasing its capabilities in 3D printing and design.
