Industrial 3D CAD engineering model of a 3-part modular internal chassis for a smart trifold wallet. Uniform 1.2mm base wall thickness, smooth 3mm filleted corners, and a matte polymer finish. Optimized for FDM 3D printing. Total Boundary Workspace: 243.0mm Width × 83.0mm Height. Three independent flat rectangular plates separated by strict 1.5mm empty air gaps. 1. Left Panel (80 × 83 × 2.5mm): Features a centered, sharp rectangular recess measuring 26.5 × 24.5 × 2.0mm deep. Includes a shallow 0.5mm deep, 5mm wide vertical wire routing channel along the far-left edge. 2. Center Panel (80 × 83 × 4.5mm): Features three dedicated component pockets: • Pocket A (MCU): 22.0 × 18.5 × 3.5mm deep. • Pocket B (Battery): 31.5 × 21.5 × 4.2mm deep with perfectly smooth interior floors and rounded corners. • Pocket C (Charger): 28.0 × 15.0 × 2.0mm deep. • Includes 1.2mm wide wiring slots cut through both the left and right interior walls. 3. Right Panel (80 × 83 × 12.0mm max): Features a wide, shallow 45.0 × 45.0 × 1.2mm deep indentation on the bottom floor. 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. Output as a unified coordinate assembly of three separate manifold solid bodies.
