Modified the original model ( https://www.printables.com/model/888192-rwb-porsche-911-964-turbo-kit-card ) that was a single part to be in more parts (body, windows, lights) so it can be printed in two colors also without prusa slicer. I also changed the wheels and tires to printed together and cura recognises them as one part.
My printer doesn't work with prusa slicer so that's the only way to get it in more colors. Uploaded as a remix in case someone else finds it useful too.
