stone castle 3d model

A 3D printable miniature aquarium hardscape model, overall size approximately 8cm in width. The design features a simple, hollow stone castle in the center with a rounded tower and a slightly eroded top, serving as a fish hiding cave with multiple small entrance holes at its base. The castle is surrounded by layered mountain rocks with rugged textures, natural crevices, and tiny caves providing additional shelter for small fish and shrimp. The entire structure mimics a natural symbiotic environment where the castle appears as an integral part of the rocky landscape. Functional elements include the hollow castle interior and hidden pockets among the mountain rocks. Realistic rock surfaces, subtle moss accents optional. Designed for FDM printing with minimal supports; parts can be printed separately and assembled. Isometric view, clay render, solid white background, 3D modeling wireframe look, soft ambient lighting. --ar 1:1
