Project Overview
Need a turnkey, 3D-printed, ceiling-mountable enclosure that integrates a Raspberry Pi 4, a USB camera module with a motorized privacy shutter, and an Adafruit-style microphone/speaker “hat,” fully designed, prototyped, and delivered within 15 days.
Technical Specifications
This solution must include a sliding bi-leaf or iris-style shutter mechanism with linear guides, linkage, and foam seals to eliminate light leaks, optimized for SLA or SLS printing with UL94-V0 ABS/PC housing and black-anodized aluminum or flocked ABS shutter blades in a matte finish.
CAD and STL Requirements
Need a fully constrained CAD assembly (STEP/IGES) and STL files for rapid prototyping, along with annotated drawings specifying tolerances (±0.1 mm).
Mounting and Features
Need clear mounting features for the Pi 4 board, camera PCB, mic/speaker PCB, and either a PWM-driven micro-servo or DRV8825-driven micro-stepper motor driver, plus integrated cable-routing channels and a removable faceplate for SD-card access and focus adjustment.
Bill of Materials
Need a complete bill of materials listing all hardware—fasteners, guide rods, motor, seals—with vendor part numbers and cost estimates.
Prototypes and Validation
Need functional prototypes printed in resin or nylon to validate fit and ensure shutter actuation in under 500 ms by Day 7, with status updates twice weekly.
Design for Manufacturing
Need a brief DFM report outlining print orientations, support minimization, and scaling notes for bridge tooling in case of future injection-molding.
Final Deliverables
Final handoff package—including CAD, STL files, drawings, BOM—by Day 15. The project must kick off within two days of hire and be structured for rapid delivery without compromising precision.
