Title: Mechanical CAD Engineer – Injection-Moulded Plastic Consumer Product / Snap-Fits / Mechanisms / SolidWorks Project description: I am looking specifically for a mechanical product design engineer with proven experience designing small injection-moulded plastic consumer products. This is NOT an architecture, interior design, rendering, animation, graphic design or general 3D-modelling project. Please apply only if you have real experience with functional plastic parts intended for injection moulding, including features such as: * snap-fits and retaining clips; * small hinges and closures; * push/release mechanisms; * mating plastic components; * controlled clearances and tolerances; * wall thickness and draft angles; * ribs, radii and manufacturable geometry; * assembly fit and basic injection-moulding DFM. The overall product concept and styling are already defined. I need an engineer who can convert the existing specification into a manufacturer-ready mechanical CAD package, without redesigning the product concept. The project mainly includes: * a small handheld plastic holder; * a small protective case; * a removable component interface; * snap-fit / clip retention; * a low-force release mechanism; * hinge / closure details; * mechanical fit between components. Required deliverables: * editable native SolidWorks parts and assembly files; * STEP/STP files for all parts and assembly; * dimensioned 2D manufacturing drawings in PDF; * exploded assembly view; * section/detail views of critical mechanisms; * critical dimensions, tolerances and clearances; * preliminary material recommendations; * basic injection-moulding DFM notes; * at least one revision after manufacturer feedback. Mandatory experience: Please do not apply based only on general 3D-modelling or rendering experience. Your application must include at least one example of your own previous work involving a small injection-moulded plastic enclosure, snap-fit, clip, hinge, closure or release mechanism. If the previous project is confidential, a cropped CAD screenshot showing only the mechanical detail is sufficient. Applications showing only architecture, interiors, buildings, character modelling, jewellery, decorative STL models or general rendering will not be considered. Please confirm in your proposal: 1. Your experience with injection-moulded plastic product design. 2. Which relevant mechanical features you have designed before. 3. That you can provide editable native SolidWorks files. 4. Your realistic delivery time. 5. Your fixed total price for the complete scope. 6. Number of revisions included. 7. That you are willing to sign an NDA before receiving the confidential specification. No work should begin until the NDA, scope, deliverables, fixed price and timeline are agreed in writing.

As a seasoned mechanical designer with 9 years of experience under my belt, I am confident that I am the perfect candidate to bring your injection-moulded plastic consumer product vision to life. Over the course of my career, I have amassed extensive experience working on projects that align precisely with your specifications. I have successfully designed snap-fits, push/release mechanisms, hinges, and closures amongst other features that would be pivotal to your project's success. All this work was done using SolidWorks, a skill that has proven to be very valuable when working with DFM and creating manufacturing-ready designs. Regarding cost, once the precise scope of the project is defined, I prefer offering a fixed total price rather than confusing my clients with added complexities mid-way. Rest assured, all this pricing will be discussed and agreed upon in writing before we commence any work- adier-ing a transparent and accountable process for both sides.

Hello, We can convert your existing product concept into a manufacturer-ready injection-moulded CAD package without changing the established styling. The focus will be on the handheld holder, protective case, removable interface, snap-fits, retaining clips, release mechanism, hinge/closure, mating fit, tolerances, wall thickness, ribs, radii, and draft angles. We’ll provide editable native SolidWorks parts and assembly, STEP/STP files, dimensioned PDF manufacturing drawings, exploded and section/detail views, material recommendations, and preliminary injection-moulding DFM notes. We can also provide a relevant example of previous injection-moulded plastic mechanism work, including a cropped CAD detail if the project is confidential. Thanks

The key challenge here is getting the snap-fits, release force, mating clearances and injection-moulding details right—not simply producing the 3D geometry. I can develop the parts and assembly in native SolidWorks, with attention to wall thickness, draft, ribs, radii, tolerances and functional interfaces. My mechanical product-development work includes detailed CAD, manufacturing-oriented design, prototyping and engineering validation. Deliverables can include SLDPRT/SLDASM, STEP, dimensioned PDF drawings, exploded/section details and concise DFM notes. I would include up to 2 revision rounds; physical fabrication/testing and substantial scope changes would be outside the agreed scope. I’m also comfortable signing an NDA before receiving confidential information. Do you already have the initial CAD/specification package and target material/manufacturing process?
