How car parts actually work on MyMiniFactory and GrabCAD
Finding parts for your car on MyMiniFactory
MyMiniFactory curates for printability, which is a real quality signal — files are checked to print successfully. That check is about geometry and print success, though, not about whether a part fits a particular vehicle, and those are different questions: a bracket can print perfectly and still be 4mm too wide for the mounting point. The platform's centre of gravity is also tabletop and collectible models, so the automotive catalogue is comparatively thin, and what is there is rarely organised by vehicle.
Finding parts for your car on GrabCAD
GrabCAD is an engineering CAD library, and its automotive content reflects that: assemblies, mechanical components and reference geometry aimed at engineers, distributed largely as CAD source formats like STEP and IGES rather than print-ready STL. The models are often more precisely specified than anything on a consumer platform. They are also frequently not printable as downloaded — wall thicknesses, tolerances and support geometry are drawn for machining or injection moulding, so using one on a home printer usually means reworking it in CAD first.
