this is my take on a 3d printed RC car. To be precise, it's a rock crawler. I call it M.O.A.W. which stands for motor on all wheels. It is a fairly simple design and intermediate hobbyist should be able to build it.
I used PLA with 100% infill for all parts. You will also need to enable support except for the hubs. Make sure you print the hub 4 times, and the body twice (you need to mirror the second one in your slicer).
