⚠️Safety Notice: Use this device entirely at your own risk. The creator accepts no liability for damage to your vehicle, other vehicles, or for any operation that conflicts with traffic regulations. Do not use on public roads. ⚠️Experimental prototype: Print this model only if you truly need it. In real-car tests, the soap splashes out quickly over bumps—this is a fundamental limitation. Still, the unit works well as a bubble machine in strong, steady wind or in front of a household fan. Car Bubble Machine is a wind-powered bubble blower that sandwiches between your car window and door frame. The 90 mm fan spins in the slipstream and, through a 6:100 gear train, turns a 12-ring bubble wheel while the same airflow inflates a cloud of shimmering bubbles behind you. 💧 Lubricate all moving parts during assembly; silicone oil works well. ✨ Key FeaturesWindow-mount design: clamps to your car’s door window glass.No electronics: pure wind power — zero motors, batteries, or wires.Right- or lef
