To begin the project, I performed a complete teardown of an old car power bank inverter to study its internal layout, circuitry, and cooling design. This process helped me understand how the inverter converts DC power to AC and how its components such as the MOSFETs, transformers, and heat sinks were arranged for efficient performance and heat dissipation. Analyzing this existing design provided valuable insight into component selection, wiring organization, and enclosure design which guided the development of my own inverter system. 

The enclosure was 3D printed using ABS material to provide better heat resistance and durability compared to PLA. The parts were printed with optimized infill and orientation to ensure dimensional accuracy and strength while maintaining a clean surface finish. Once printed, the top and bottom sections aligned precisely with the screw holes, confirming that the design translated well from CAD to a physical prototype suitable for housing electronic components that generate heat. 

The inverter components were carefully assembled inside the 3D printed ABS enclosure. The circuit board was positioned to align with the ventilation slots and power socket openings, ensuring proper airflow and accessibility. The fan and connectors were securely mounted, and the internal wiring was routed to prevent interference with moving parts or heat-sensitive areas. After verifying all electrical connections, the enclosure was closed using screws at each corner, completing a clean and functional assembly ready for power testing and use.
