Insanely Fast and Powerful High Gear Ratio 3D Printed Gearbox

This gearbox has uses 4 350W DC motors for ULTIMATE POWER. How fast can it go? The high gear ratio gearbox has a very high gear ratio, which means if we spin the first gear, the last gear will spin extremely fast. But this time, I’m powering it with FOUR massive electric motors. Let’s build it and see how fast it can go! Learn how to 3D print: Best 3D Printers: Happy printing! -Steven
