Inspired by Thing-O-Fun's "Functional Differential Gear System" I decided i should make one for my RC car. So i did.
I scaled down the gears from the above mentioned Thing, and designed the rest of the parts in my favourite cad software.
And it works surprisingly well, my car is 4WD so i have two of these in the car right now!
The parts may have some adjustments done to fit the settings of my printer so you might have to do some adjustments of your own to make it fit correctly.
The "Side Gear Axle" is made of 3mm stainless steel.
Other than that check out the exploded view PDF to see how itÂ´s assembled.
I made this as an experiment so you should consider it as beeing such a thing.
