Just print all of the main body parts:

Ferrari part 1.stl
Ferrari part 2.stl
Ferrari part 3.stl
Ferrari part 4.stl
Ferrari part 5.stl

We recommend using a raft with a low infill around 10%. We recommend using support on Ferrari part 5.stl as there is a overhang that will not print without support.

For the wheels you will need to print the rest of the parts with a higher infill around 40% with raft and support.

Once you have all the printed parts assemble the list of parts above by gluing them together and then place some glue in the slot and place through holes on model and insert other half and press firmly to attach wheels together. Once you have all the parts together you can then try and finish off the model if you like with sand paper or together materials.
