The prompt
Create a 3D-printable outer silicone enclosure for a compact wearable biosensor inspired by the BAMS device. Overall dimensions: 40mm length, 20mm maximum width, 8mm maximum height. Create a soft, elongated medical wearable shape with smooth rounded edges and corners. Use rounded outer corners with approximately 3mm fillets. The main body should have a rounded rectangular shape, with a narrower flat extension tab at one end, similar to the BAMS wearable sensor. Extension tab dimensions: approximately 10mm length and 10mm width. Add one small circular hole near the end of the extension tab, approximately 2mm diameter. The enclosure should have a smooth slightly raised central area to cover the flexible PCB, battery, IMU, microphones and wireless electronics. Design the enclosure as a two-layer silicone shell: - Top silicone cover - Bottom silicone cover Leave an internal cavity between the two silicone layers for the flexible PCB and electronic components. The silicone wall thickness should be approximately 2mm. Add a small acoustic opening on the top surface for the external microphone. Add a corresponding acoustic opening on the bottom surface for the skin-facing microphone. The bottom surface should be smooth and slightly curved for comfortable contact with the skin. No hard plastic box, no screws, no hinges, no strap slots, and no sharp edges. The final shape should visually resemble the white BAMS wearable sensor shown in the reference image.
