3d diorama model

A detailed 3D diorama based on a rectangular base. The model must prioritize physical geometry and high-relief details for 3D printing. Features include: high jagged mountains with snowy peaks in the back; a deep, carved winding riverbed crossing from the mountains to the front; on the left, 3D embossed trees and small volumetric houses with gabled roofs; on the right, a blocky industrial factory with tall cylindrical chimneys and a rectangular treatment plant with visible pipes connected to the river. The terrain should have different height levels to distinguish land from water physically. Style: Thick solid volumes, clean edges, manifold geometry, no flat textures, high relief, isometric composition.
