Volume-Measuring Bottle Design -- 2

I am seeking an Industrial Designer or Mechanical Engineer with CAD specialization to translate existing conceptual sketches into professional, manufacturing-ready CAD files for a consumer beverage bottle and custom closure system.

Scope (high level):
– Create 3D parametric CAD models (SolidWorks or Fusion 360 preferred)
– Bottle exterior geometry and a multi-component closure (functional details to be shared post-NDA)
– Conceptual section views and exploded layout for design review
– Prepare files suitable for prototyping, patent figure refinement, and manufacturer feasibility review

Deliverables:
– STEP / IGES files
– DWG / DXF drawings (non-confidential views only at this stage)

Important notes:
– This is a paid consulting engagement
– Detailed dimensions, tolerances, internal mechanisms, and proprietary features will be disclosed only after NDA execution
– Prior experience with consumer packaging, bottles, closures, or injection/blow-molded parts is strongly preferred

The goal of this phase is to confirm technical fit and workflow compatibility before proceeding to a full technical brief under NDA.
