I looking to have a toy car chassis/ frame designed. I need a 3D model made in .stl format so that it can be 3D printed. The photo is just a starting point, i need to keep the overall shape and concept the same but it can be simplified. I need a simple front and rear axle added to the car. I do not need fine details. It needs to be split into 3 sections, everything in front of the cockpit, the cockpit itself and everything behind the cockpit.
