desert rock wall 3d model

A rectangular terrarium rock background wall for reptiles, designed as a 3D printable bas-relief panel. Overall shape: wide horizontal rectangle, 1000 mm width, 400 mm height, maximum depth 22 mm. The wall must be much wider than tall, almost 2.5:1 proportion. Back surface completely flat for mounting against terrarium glass. Front surface only contains the sculpted relief. Style: natural desert canyon sandstone rock wall, realistic layered sedimentary geology. The rock formations must run horizontally from left to right across the full width of the panel. Include long horizontal rock ledges, flat reptile basking platforms, weathered erosion grooves, natural cracks, and several shallow cave recesses carved into the rock. Lower section: include a twisted dry desert tree root emerging from the rock near the bottom, extending horizontally across the wall, partially embedded into the stone surface. The composition must remain low relief and wall-like, not a freestanding sculpture. No vertical towers, no tall
