Create a detailed 2,5D model for cnc machining

The 2,5D model is needed in stl/step format, to be used to manufacture a set of doors for an iconostatis in an orthodox church. The composition of the model should be inspired by the photos named "Inspiration 1-3" , and the outer edge of it should not exced the limits that could be found in the attached dxf. The photos named "1.jpg" , "2.jpg" , "3.jpg" and "4.jpg" are an unfinished 2.5D model of how the door should look like. There is no need for advanced rendering skills, no textures or lighting, only simple 3d model.
