terrarium hide 3d model

Generate a single-piece, watertight (manifold) 3D model of a two-tier terrarium hide for a leopard gecko (Eublepharis macularius) with an integrated ramp. The model must be strictly monolithic—no separate parts, no removable lids, no assembly. Units in millimeters, Z-up, oriented flat on the build plate. Style: natural rock/sandstone with soft, non-sharp micro-texture for grip. BUILD VOLUME - Entire model must fit within 220 × 220 × 250 mm. Target envelope ≤ 210 × 210 × 180 mm to allow slicer margins/brims. OVERALL SIZE & LAYOUT - Footprint (base): ~210 × 160 mm; overall height: ~120–130 mm. - Lower level (main hide): internal cavity ~160 × 110 × 70 mm (L × W × H). - Entry arch to the hide: ~60 mm wide × 50 mm tall; edges filleted (R = 3–5 mm). - Upper level (lounging deck): ~200 × 120 mm at ~90 mm Z height. - Integrated ramp from lower to upper level: width ≥ 60 mm, slope 15–18°, shallow cross-rungs 2–3 mm high at 10–12 mm pitch; side curbs 5–8 mm tall. - Ventilation: rows of Ø3–4 mm holes on rear/side wal
