iPhone 15 Smart Case Industrial Design

About the project

We're developing a premium smart case for the iPhone 15 ("Techs") housing a custom PCB, battery, ESP module, and a 1.69" TFT display (240×280, ST7789) positioned beside the camera. This is a real hardware product going to manufacturing — not a concept render. We need the complete enclosure design taken all the way to production-ready files. Scope — full enclosure design: Precisely fitted to iPhone 15 dimensions (camera module, buttons, ports, charging alignment) Body + lid + internal PCB housing + battery compartment + display window Slim, pocket-comfortable profile despite housing electronics iPhone-recognizable silhouette (camera cutout, optional Apple logo visibility) Our brand logo ("Techs") engraved/embossed or otherwise integrated into the case design — placement and execution style open to your suggestion Electrical insulation — no electronic component may directly contact the iPhone body (hard constraint, full guideline PDF provided) Thermal consideration — heat from electronics must not be trapped against the phone Fastening/assembly method that's fast for us to assemble in production but not user-openable Drop-resistant, good tactile feel, balanced weight Surface finish suitable for printing/branding Deliverables (fully manufacture-ready): Final 3D CAD files (STEP + native format) Complete technical drawings with tolerances DFM/DFA validation for the chosen manufacturing process Material selection with justification (mechanical, thermal, cosmetic) Manufacturing process recommendation — CNC prototype and/or injection molding for production — with reasoning Files ready to hand directly to a CNC shop or mold maker with no further engineering needed Agreed number of revision rounds included (please state how many rounds are included in your quote) We will provide: 3D model of the PCB Full electronics specs (battery, display, ESP, charging port) Techs logo file (vector) Design guideline PDF (critical constraints, e.g. electronics-to-body clearance) Reference iPhone 15 CAD dimensions if needed Budget: $100–150 fixed, full scope as described above. Please quote within this range and note if any part of the above would need to be trimmed to fit it — we'd rather know upfront than mid-project. To apply, please share: Portfolio of enclosure/electronics-housing designs that were actually manufactured (not just rendered) — plastic or metal parts Software you work in (SolidWorks / Fusion 360 / Inventor / etc.) Your experience with DFM/DFA and injection molding or CNC part design Estimated turnaround time and number of revision rounds included at this budget
