Reduction Gearbox Gear Ratio

Ultimate Super-Reduction Gearbox (262,144:1) – 3D Model Kit

Explore massive torque multiplication with this fascinating engineering model. Featuring a mind-blowing 262,144:1 total gear ratio (achieved via nine stacked 4:1 compound gears), it's the perfect desk toy or educational tool to demonstrate gear ratios.

One crank is extremely 'light' (requiring 262,144 turns for one rotation on the other side), while the other is immovably 'heavy'. The modular design snaps or screws together easily and allows you to customize the gear count.

This is a remix. I have modified the original model to significantly reduce print time and improve tolerance. The design is optimized to ensure a perfect print on Anycubic printers and similar machines.
