This project is dear to me in many ways! I spent a large chunk of my mechanical engineering undegraduate studies working on it slowly and now I am happy to share it with all of you! It is possible to 3D print it, so I have broken it up into several sections, including the main body, individual wheels and the front wiper! It will take some work to get the support right, especially for resin, but it is a beautiful model indeed. If you want the source Solidworks file, let me know and we can work something out. That way you can customize it even further.
