I am working on a Raspberry Pi car project, and I am at the point where I need to make it very specific. So far I have been using a Raspberry Pi car kits that are found everywhere, but they come with so many things that are not useful for me and don't meet my exact needs in terms of shape and size. So I want to build my own car chassis for custom wheels etc. Where can I get this done? Will I have to create a 3D model of my design and send it to a 3D printing service and get it printed, or how does this work exactly. How do people do it when it comes to creating your own car chassis for the Raspberry Pi.
Any info regarding this would be greatly appreciated.
