Not sure if this is the correct place to upload, but seemed most fitting. I did some half assed 3D reconstruction of the engine bay of my car just to have some reference to build against in CAD. The scans are far from perfect, but definitely usable if you want to get some measurements and figure out if your parts will fit in the bay. 1999 Miata with a BP4W engine.
Models are in metric scale (mm units) and should be level with X pointing forward and Z up. One is the full engine bay, and one is only the intake region in a slightly higher detail. I also included an picture of an example use case. I recommend ignoring the textures and importing the .OBJ directly to CAD to block out a clean model if you want to do smth useful with this, but I included the textures if someone wants to see the details.
