This is an axle for any RC car depending on what type you have. It should work for most cars, and you can adjust the hole sizes if needed. This took a lot of iterations because I wanted it to be a tight fit for my car so it wouldn't move around. Other than that, I just modeled it first try! One thing I would want to improve or someone can do a remix is adding more support on the cylindrical pieces because they can break after a long while after “abusing” a lot. I torture tested the axle by driving it over rocks and dirt and water, and broke after like 40-60 minutes.
