I needed a body for my DR10 rc car. I had this model and scaled it to use on my rc car. You will probably need to scale it to fit your use case, because the one in the print profile i published was actually a bit small for my car. I am printing a new one now, but since it takes about 20 hours to print i will update this post later with another profile.

The edges of the body has holes where you can insert small pieces of filament to line up the two pieces perfectly.
