Industrial 3D CAD engineering model of a 2-part modular internal chassis for a smart bifold wallet. Uniform 1.2mm base wall thickness, smooth 3mm filleted outer corners, and a matte polymer finish. Optimized for FDM 3D printing. Total Boundary Workspace: 220.0mm Width × 85.0mm Height. Two independent flat rectangular plates separated by a strict 1.5mm empty air gap for the center folding hinge. 1. Left Panel (109.25 × 85.0 × 4.5mm max) - Sensor & Power Core: • Features three dedicated component pockets: • Pocket A (RFID MCU): 26.5 × 24.5 × 2.0mm deep. • Pocket B (Battery Armor): 31.5 × 21.5 × 4.2mm deep with perfectly smooth interior floors and rounded corners. • Pocket C (Logic Brain): 22.0 × 18.5 × 3.5mm deep. • Hinge Exit Interface: On the inner right vertical wall facing the center hinge, feature a 10mm wide horizontal exit slot. The outer mouth of this slot must have a smooth 1.5mm radius downward bevel (chamfered curve) to eliminate sharp edge contact with exiting cables. 2. Right Panel (109.25 × 85.0 × 12.0mm max) - Locking Engine & Induction: • Features a wide, shallow 45.0 × 45.0 × 1.2mm deep indentation centered on the bottom floor for an induction charging coil. • On the far-right edge, features an extruded 25.0 × 15.0 × 12.0mm solid mounting block with a hollow cylindrical center cavity and two vertical M2-clearance through-holes for deadbolt anchoring. • Hinge Exit Interface: On the inner left vertical wall facing the center hinge, feature a matching 10mm wide horizontal exit slot with a smooth 1.5mm radius downward bevel on its outer edge. Output as a unified coordinate assembly of two separate manifold solid bodies showcasing the mirror-symmetrical curved stress-relief exit zones at the center hinge gap.
