Gearbox

Hello everyone, here are my new gearbox with 3 gears and neutral, it is very simple but functional.

The proportions of the input shaft with respect to output are:

Neutral 0:0

First 5:3

Second 1:1

Third 1:3

These Gearboxes are very easy to build, for add more gears, only you have extending the axes and add more gears combinations, can be up to five more neutral gear.

Well, I hope you like. Soon I will upload the instructions.
