I'm taking a true-wireless earbud concept into the industrial-design phase and need production-ready CAD for three plastic parts: the earbud housing, a matching charging case, and a clip-on sports accessory. You'll be starting from concept renders and basic component envelopes I already have dimensioned. Earbud housing Organic crescent form — no sharp edges, all transitions soft and continuous. The shell must follow the natural curve of the concha for an ergonomic fit while leaving internal volume for an 8–10 mm dynamic driver, small LiPo cell (~60–80 mAh), and BLE SoC board. Parting line at the lateral midplane. Gasket seats and microphone port array on crown. Charging contacts (3× pogo pins) on lower stem. Inner face has a flat sensor contact pad ~12×8 mm. Charging case Compact and portable — closer to a polished pebble than a bulky brick. Form-fitted interior cavity shaped to the earbud. Room for a 500 mAh Li-ion pack, USB-C PCB, and twin pogo-pin nests. Magnetic lid closure, subtle status-LED window. Draft angles and snap-fit ribs suitable for single-shot ABS or PC/ABS injection. Clip-on accessory A three-arm flexible extension that locks onto the earbud magnetically for extended wear. Arms in TPU or silicone overmould, each terminating in a small contact pad. I'll provide the attachment interface geometry; you'll flesh out the surfacing so it moulds cleanly. Deliverables — Parametric 3D models in STEP + native Fusion 360 or SolidWorks files — OBJ or FBX export for rendering — Basic 2D drawings calling out critical tolerances, draft angles, and parting lines I can supply reference images and component dimensions immediately on award. Ready to move fast.

Sir: Your needs are very clear. I use PTC/Creo. I have been doing product design since 2008. I have designed many products and opened molds to complete production and assembly. I have rich design knowledge in mold molding and 3D printing design. Because in the early stage of product development, I need to confirm the prototype assembly through 3D printing before preparing to communicate with the mold processing factory for DFM. Confirm the injection gate position, uniform wall thickness, mold flow analysis, parting line position, etc. The plastic material needs to be determined during product development, because different materials cannot be injected with the same mold. I can respond to your instructions quickly and ensure that the task is completed within the specified time limit. Because all these tasks are completed by me alone. I hope to cooperate with you and serve you. I hope to get your response

Hi, I went through your brief and this is a full consumer electronics industrial design task where manufacturability, internal packaging, and injection molding constraints matter more than surface styling. I can develop production-ready CAD for the earbud housing, charging case, and clip-on accessory with proper internal volume planning, clean parting line strategy, and injection-molding friendly geometry including draft angles, snap fits, and gasket and contact seating. The design will be structured parametrically in Fusion 360 or SolidWorks with clean STEP exports, along with supporting 2D drawings that clearly define tolerances, assembly logic, and functional interfaces for drivers, PCB, battery, and magnetic systems. I’ve worked on similar compact wearable and enclosure design pipelines before and can share relevant examples once we connect in chat. Quick question: is your priority more focused on maximum acoustic performance (internal volume optimization) or achieving the smallest possible form factor for the earbuds? Best Regards, Muskan

Hello, I have extensive experience developing consumer electronic enclosures and wearable products, including TWS earbuds, charging cases, injection-molded accessories, and ergonomic soft-surface assemblies for mass production. I’ve created production-ready CAD for compact electronics with complex surfacing, internal component packaging, snap-fit construction, gasket interfaces, magnetic attachments, and mold-ready geometry optimized for ABS, PC/ABS, TPU, and silicone manufacturing workflows. For your project, I will develop clean parametric CAD models for the earbud housing, charging case, and clip-on accessory while maintaining ergonomic comfort, manufacturable surfacing, and internal space allocation for the electronic components you specified. The models will include draft-aware parting strategies, gasket and charging-contact integration, magnetic alignment features, and injection-molding considerations suitable for prototyping and future tooling. STEP, native Fusion 360 or SolidWorks files, OBJ/FBX exports, and basic engineering drawings with key tolerances and parting-line references will all be prepared for production and visualization workflows.
