Here is the print of the OpenRC Formula 1 chassis plates, finished and assembled. Take note of the screw/nut positions. My model was printed with the intent to display it. Because of this, I am not sure if the screw/nuts are in the way of the electronics needed to make it a remote control model. Each plate was positioned in my slicing software to eliminate the need for supports. This causes each chassis plate to have 2 different appearances when viewing the underside of the car. If the underside of your OpenRC F1 project is important for consistency than support will be needed.
