These doors are part of my 3D Printable model of Volkswagen Golf II 'Country' version - body and interior, which you can find here:

https://www.cgtrader.com/3d-print-models/hobby-diy/automotive/volkswagen-golf-ii-country-body-and-interior

Uploaded on customer request.

Contains only the 4 doors, as you see them on the preview images - each one on a separate STL file.

Plus another file containing only the interior door panels separated from the doors - all in one STL (see the last preview image).

If you need the whole car model and more info, check out the original model from the link above.
