Industrial CAD Design for a 3.75L Modular Blown-Glass Mezcal Bottle (Identical Interlocking Segment)

Job ID: 40500258

Budget: $750 – $1,500 USD

We are launching a high-end, limited-edition (50 sets) collaboration between a fine artist and a luxury Mezcal company. We need an experienced Industrial Designer or Mechanical Engineer to design a single, modular, food-safe glass bottle that functions as part of a larger interlocking sculpture.

The final assembly stands 18 inches tall and resembles a "blue barrel cactus." This sculpture is composed of five (5) completely identical wedge-shaped bottles (like segments of an orange) that radially array to form the complete 3D cactus.

Because you only need to design one single bottle that repeats five times, your focus will be entirely on perfect geometric tolerances, liquid volume calculations, and manufacturing feasibility for heavy blown glass.(Note: The finished bottles will eventually sit in a custom ceramic base designed separately, so your focus is purely on the glass engineering).

Key Technical Requirements:
Software: Must be designed using parametric CAD software (SolidWorks, Autodesk Inventor, or Rhino 3D). No Blender, Maya, or polygon mesh files will be accepted.

Interlocking Geometry: The left and right faces of the wedge bottle must feature flush tolerances or subtle interlocking channels so that 5 identical copies sit tightly together in a circle without slipping or wobbling.

Volumetric Accuracy: The internal cavity of the single wedge segment must hold exactly 3.75 Liters of liquid. This must include a standard 5% headspace allowance for liquid expansion and standard cork depth insertion.

Neck & Closure Integration: The neck of each identical segment must terminate at the top point of the wedge. The neck must be engineered to a standard T-Top Cork / Bartop finish (e.g., 19.5mm or 21.5mm inner diameter). When all 5 bottles are assembled, the 5 individual corks must cluster closely together at the peak to visually form the "crown of flowers" of the barrel cactus.Manufacturing Constraints: The design is for a production run of hand-blown glass using metal molds in Guadalajara, Mexico. Because of the 3.75L volume, the designer must engineer thick, structurally reinforced glass walls (minimum 8mm–10mm) and respect glass-blowing physics (realistic radiuses, proper draft angles for mold release).

Deliverables Required:
Source CAD Files: Native files (SolidWorks/Rhino) along with universal .STEP or .IGES files for CNC mold-making.Production Blueprints: 2D technical drawings (PDF) with exact dimensions, wall thicknesses, and neck/finish specifications for standard closures.

Assembly Render: A basic 3D exploded view rendering showing how the 5 identical pieces slide together to form the 18" cactus.
