The prompt
Create a rectangular 2-part clamshell project enclosure box for a small electronics build. Dimensions: 65mm length, 45mm width, 22mm height with filleted rounded corners. The top piece should secure tightly to the bottom piece via small internal friction snap-joints. On the top face, place three circular cutouts in a linear row for tactile micro-switches, each hole measuring exactly 6mm in diameter. On one of the narrow side walls, create a precise rectangular slot cutout measuring 12mm x 5mm for a Type-C USB charging port. Right next to it on the same wall, place a slim rectangular slot measuring 15mm x 3mm to allow access to a Micro-SD card slot. The wall thickness of the entire box should be a uniform 2mm. Ensure the mesh topology is watertight, single-shelled, and fully optimized as an STL file for FDM 3D printing.
