gecko terrarium 3d model

Generate a SINGLE-PIECE, watertight (manifold) 3D model of a TWO-TIER terrarium hide for a leopard gecko (Eublepharis macularius) with a STRAIGHT, EASY-CLIMB RAMP (ladder-like tread pattern). No separate parts. Units in millimeters. Z-up. Orient flat on the build plate. PRINTER ENVELOPE - Entire model must fit inside 220 × 220 × 250 mm. - Target outer footprint ≤ 205 × 160 mm; overall height 120–130 mm. SMOOTH WALLS (critical) - All exterior and interior walls must be SMOOTH (no rock noise, no micro-bump). Surface roughness amplitude ≤ 0.05–0.10 mm. - Vertical walls planar and orthogonal: 90° ± 1° to the floor. - All edges filleted (R = 3–6 mm outside, R = 2–4 mm inside). No sharp points. FLAT INTERIOR FLOOR (critical) - Interior floor perfectly flat, 0° slope, clear rectangle 165 × 115 mm. - Floor Z = +5.0 mm above the external bottom (base thickness under floor = 5.0 mm). - Apply a 0.3 mm × 45° anti-elephant-foot chamfer ONLY on the OUTER bottom perimeter (do NOT chamfer the interior floor).
