Create a 3D model (.stl) of this house for 3D printing

3d model in .stl format

Greetings sir. I have attached the 3d model of the house as per the given scale. Windows and doors are empty just like given in the example. GF, FF, and Roof are in separate layers, so they can be edited easily. If you need any changes please let me know I will do it acordingly. Thank you.
