Smart Glasses Temple Arm Enclosure

Design a highly precise, sleek, two-piece electronic wearable enclosure (smart glasses temple arm casing) accommodating a microcontroller, a Li-Po battery, a charging module, and a micro speaker. 1. Overall Form & Internal Cavity: - Create a long, rectangular hollow sleeve. - The INTERNAL hollow cavity MUST measure EXACTLY 96.0mm (Length) x 24.0mm (Width) x 12.0mm (Depth). - The 12mm internal depth is critical to stack a 5mm Li-Po battery underneath the circuit boards. The internal walls must be perfectly flat. 2. Screw Standoffs: - Place four screw standoffs (for M3 screws) at the absolute extreme corners. - DO NOT let the screw pillars protrude into the central 24mm width of the cavity. Push or embed the pillars entirely into the outer wall thickness so the inner rectangular space remains completely unobstructed for the battery and boards. 3. Enclosure Features & Cutouts: - Front Wall (Short side): Cut a clean horizontal slot measuring EXACTLY 16.0mm (Width) x 1.5mm (Height) for an FPC camera ribbon cable. - Side Wall (Long side): Cut a 12.0mm wide horizontal slot for MicroSD card access, positioned 15mm away from the front wall. - Speaker Grill: Cut a series of small 1.5mm circular audio holes (speaker grill) on the outer side wall for sound output. - Rear/Bottom Wall: Cut TWO separate openings for USB Type-C ports (one at the rear end for the charging module, one on the bottom edge for the Pico data port). - Top Lid: Provide a completely separate, flat, removable lid that fastens into the four corner screw holes. 4. Mounting Mechanism: - Add a slim, rigid C-clip or dual mounting hooks on the inner side wall, designed to securely snap onto a standard glasses temple arm.
