Propeller Car V2

LouVee Air Car V2 - Rubber Band Powered Wind Spinner Car A fully 3D-printed LouVee air car redesigned for the Wind Spinner Design Contest as a more functional, reliable, and classroom-friendly build. The model only needs rubber bands to run and demonstrates stored energy, airflow, friction, motion, and basic mechanical design in a simple hands-on way. This V2 keeps the recognizable LouVee air car concept, but the design has been rebuilt for better performance and easier printing. The biggest change is the new press-and-lock wheel and shaft system, which makes assembly easier, keeps the wheels better aligned, and fixes the drift issue from the earlier version. As a result, the car travels much straighter when propelled. The updated parts use less filament, print faster, and are less prone to breaking, especially around the wheel shafts. The cleaner geometry also makes the model more repeatable for classroom use, STEM demonstrations, or anyone wanting a simple rubber-band-powered enginee
