STEMFIE Infinity Gears

The STEMFIE Infinity Gears project is not just a playset but an educational tool that illuminates the mechanical principle of gear reduction through six steps. Each module features two gears on one axle: the small gear with 17 teeth and the large gear with 58, resulting in a 3.41 gear reduction. This means that for each complete turn of the initial 17-tooth gear in the motor axle, the corresponding 58-tooth gear in the sixth last stage turns about 0.0634% of a full rotation, significantly reducing the speed and increasing the torque at the output of the final stage compared to the input at the first stage. The TT motor turns at roughly 60 rotations per minute. As the gear wheels transfer rotation through each step, the last axle seems almost to remain motionless. This educational toy is made of STEMFIE components; therefore, it is modular and can be expanded. If you 3D-print more parts, how many more gear wheel reductions can you make by extending the main beam? ⚠️ Please be cautious w
