This is a Mario Kart controller for Nintendo Switch joycon controllers. I got Mario Kart (great game) but found that the controllers were quite expensive. I spent some time building something that was easy to print and where the buttons used for throwing items at other drivers were easy to reach. The wheel is nice and small for kids and easy for adults to use too.

I may publish a bigger wheel later on if there's any demand for it.

This one model has saved me the price of 4 controllers. I hope you find it useful.

This is why we have 3D printers!
