PCB enclosure

Design Constraints: PCB Fit: The internal dimensions must accommodate a PCB measuring 50mm x 70mm. Include four 2.5mm diameter standoffs in the base to mount the PCB, arranged in a 45mm x 65mm rectangular pattern. Lid Mechanism: The lid must attach to the case using a secure snap-fit mechanism. I/O Cutouts: The enclosure must have precise cutouts for the following components located on the PCB's 50mm edge: One USB-C port (10mm x 5mm). One 3.5mm audio jack (7mm diameter circle). Overall Dimensions: The external dimensions of the assembled enclosure must not exceed 55mm (W) x 75mm (L) x 20mm (H). Indicator Light: Include a small, 3mm diameter through-hole on the lid to allow light from an on-board LED to be visible.
