This project covers the complete technical development of a 250 mL premium cocktail pre-mix container in food-grade PET. I need a production-ready 3D CAD model that balances eye-catching shelf appeal with the practical demands of high-speed filling lines—good conveyor stability, reliable top-load performance, and smooth, repeatable handling by grippers. Key engineering points • Accurate volumetric and overflow calculations so the nominal 250 mL fill is achieved within standard tolerances. • Ergonomic form that feels secure in hand yet nests efficiently on pallets. • Closure design: I currently favour a screw cap but I am open to fresh ideas (foil seal or a custom neck finish) if you can demonstrate clear functional or branding benefits. • All geometry must respect blow-moulding constraints for PET, including appropriate draft angles, wall-thickness distribution, and material stretch ratios. Deliverables 1. Native 3D CAD file (SolidWorks, STEP, or comparable neutral format) of the complete container. 2. Brief calculation report showing brim-full volume, headspace, and overflow data. 3. Fully dimensioned 2D technical drawing set suitable for tooling release, including neck finish specs and critical tolerances. Timeline Everything needs to be wrapped up within a month, allowing a short review cycle for minor edits before final sign-off. Acceptance I will consider the work complete once the drawings are cleanly toleranced, the CAD passes a quick interference check in my own software, and the volume report confirms <±1 % variance at 20 °C. If you have recent PET bottle or beverage-pack experience—especially with SolidWorks, Siemens NX, or CATIA—and can meet the timing, I’m eager to see how you would approach this challenge.

Hi, I'm Krishna, an engineering student and freelance CAD designer. This brief is the kind I enjoy: a bottle that has to look good on shelf and still survive a high-speed line. My approach is to work back from the fill spec, setting brim-full volume and headspace so 250 mL is met at 20 C inside your 1% band. Then I develop the body around conveyor stability, top-load and gripper contact, with base ribbing and panel geometry that resists panelling. Geometry stays blow-mouldable throughout: sensible draft, wall-thickness distribution and stretch ratios. I model parametrically in SolidWorks and hand over native files plus STEP. You would get the 3D model early for your interference check, a fully toleranced 2D drawing set with neck finish specs, and the report covering brim-full, headspace and overflow. One month is comfortable, with room for a review cycle. On the closure, I would start with a screw cap on a standard neck finish for simple tooling, and show an alternative alongside it if there is a real functional or branding gain. Questions: preferred neck finish standard or cap supplier? Target bottle weight and resin grade? Still or carbonated, and any hot-fill? Label dimensions the panel must suit?

Hello, I can develop the complete 250 mL PET cocktail premix container as a production focused design with both shelf appearance and manufacturing performance in mind. I have strong experience in SolidWorks product development and can create the bottle geometry around the required fill volume, headspace, conveyor stability, top load strength and handling requirements. I can also review the screw cap concept and neck finish and suggest alternatives only if they give a clear functional or manufacturing advantage. The design will consider PET blow moulding requirements including draft, wall distribution, stretch behaviour and tooling limitations. I can provide the native CAD, STEP file, full dimensioned drawing set and a short calculation report covering brim full volume, nominal fill, headspace and overflow values. I will also keep the model clean and parametric so minor revisions during the review cycle can be handled quickly. if you want to discuss more about this then please send me a message so we can connect.
