Create 3d model for Air Condition Outdoor Unit and insert it into a 2d picture in a realistic way

This project is about creating the 3d model for an outdoor air condition unit. There are a few pictures of the unit attached here but a more detailed video will be provided. Then the 3d model should be imported to a 2d picture (also attached here). Finally we need to add the two L shape legs on which the unit will sit and a water extraction tube/pipe (more details about that will be provided).

The 3d model files should be provided along with the picture.
