mini pc case 3d model

Create a compact mini PC style case designed for a smartphone running Samsung DeX. The case must be hollow inside with an empty internal cavity to place components such as a USB-C hub, cables and small peripherals. Include a vertical phone dock to hold the smartphone securely aligned with a USB-C cable. The rear panel must have openings for hub ports: HDMI, Ethernet, USB-A, USB-C, SD and MicroSD. Add internal space and mounting points for components but keep most of the interior open. Include support for one 120mm cooling fan with screw holes and ventilation grill. Use hexagonal ventilation patterns on side panels. Design airflow from front vents to rear fan exhaust. The case should look like a small modern mini PC tower. Style: tech, matte black, compact, optimized for 3D printing with removable panels.
