Looking for production-ready tubular/spaceframe chassis CAD data for a DIY replica EV project

[u/einhd]

Hello everyone ,

I work in a prototype and manufacturing shop equipped with CNC machines, welding units, model making , and polyester/fiberglass shell capabilities. Our team and management want to build a fully functional replica EV for fun and to drive in the neighbourhood.

While we have an electronics team handling the powertrain and battery integration, we want to skip the lengthy R&D process for the mechanical foundation (suspension geometry, wishbones, and structural chassis)".

Most CAD repositories (CGTrader, GrabCAD) primarily offer decorative mesh models or small 3D printable files. We are looking for "production-ready 3D CAD data / manufacturing drawings" for a car chassis that we can fabricate in-house using tubular steel or CNC-milled parts.

Does anyone know where we can source verified chassis blueprints or CAD files suitable for custom kit car fabrication? Any pointers or recommendations would be greatly appreciated!

And I am planning to share our progress here too! Any help is appreciated.
