The Flutter Scout RC Car is created by Alexander Taylor and all the credit goes to him.
Here, I have special split parts of the original parts that are too big for a smaller 3D printer to print. Together with the sliced-into-2 parts, I provided add-ons which should be attached as reinforcements to strengthen the joint of the sliced parts. Simply use 3M double-sided tapes to stick on the add-ons and the sliced parts will become as strong as the original one-piece.
As the original files posted by Alexander on Github are not in STL format, I also provided a zip file comprising the whole set of files that you need to print this car (including the sliced parts, the reinforcement add-ons and an explosion-view-diagam).
Also, watch the below video to get a better picture of how the custom parts are assembled.
