This is the first attempt to spin this high gear ratio 3d printed gearbox using a cord-less drill. I also show you how to set up the gearbox it you want to try it out yourself. 3d printed on an Ender 3.

It broke my current record of ~7000 RPM
New record: ~9000 RPM

Follow along as we 3d print different gearboxes, try different gear ratios, explain the science behind these mechanisms.
