Essential Mechanisms. 3:1 Gear Box

The third project in my Essential Mechanisms series. The Gear Box can be built as a pure mechanism or as the starting point of your own character designs. The gear box has a 3:1 speed reduction with the output driving a pushrod via a crank.

Other Essential Mechanisms. I'm planning a series of mechanisms which can be built as either pure mechanisms or as starting points for your own animated paper models. There are three in total so far with many more to come.
