About this 3D model

Perfect printable drift wheel for 1:10 scale on-road rc cars. They are so smooth, they glide on carpet track no problem. They have barely any friction when sliding.

I integrated an arduino into this car with custom code to get the signal from my radio's 3rd channel to be able to change color without touching the car.
