Hi, i am an expert GIS developer, i can do this work for you.
Is your model only required for visualisation purposes? Does the 3d model need to retain coordinates etc?
I have not created a 3D model of your data yet, but attached you will find an example of the elevation surface of your data. Converting this surface to a 3D model should be a straight forward process.
How much detail does your model require? Do you want to retain the full resolution of your points?
