anti-theft sensor 3d model

Design a functional 3D enclosure for a university prototype of an IoT anti-theft system called "Anti-Theft Sentinel". The enclosure must have a TRIANGULAR PRISM shape (isosceles triangle base), designed to stabilize and fit an ESP32 development board, loose electronic modules (no custom PCB), sensors, and small actuators. General requirements: - Overall dimensions: approximately 120 mm (length) × 80 mm (width) × 45 mm (height) - The triangular shape must provide internal flat surfaces and mounting standoffs for electronics - Rounded external edges for durability and ease of installation - Made of plastic (ABS or PETG suitable for 3D printing) Functional features: - Ventilation slots on the side faces for passive heat dissipation - Two circular holes (≈5 mm diameter) on one face for external LEDs visibility - One rear cable exit opening for power and signal wires Magnet mounting: - Include an internal rectangular compartment on the flat bottom face to insert a neodymium magnet - Magnet size: 30 mm × 10 mm
