3D ecto1 help needed!

Hi everyone!

Since I have bought a 3D printer , I was looking for a 3D model of an ecto . There are a few out there, but I recently acquired a good 3D file but… I have little to no experience in modeling or editing these files…can someone help me out? I just need the file to be altered so that I just have the car body as a shell and to be able to print it for my Matty figures. I can provide the file for free if you want to give it a shot.

If possible , the car should be altered in a way that doors have simple hinges like the Kenner model. The hood doesn’t need to open, would be great if possible, and the trunk needs to open as well, I know it is a lot to ask but it would be greatly appreciated!
