Too many polygons for such a simple model. I recommend that you redo this model (I had the same problem, but I was able to get +-4 thousand from +-3 million polygons without losing the quality of the model)

Materials for this 3D model are made in the Blender.
If you need to change the size of the model or change anything in it, you can upload it to any 3D package and scale it as you like or you can do it in your software that supports 3D model formats. Preview images are rendered in Eevee Render.
I am happy to answer any questions you might have about the model.
