OBJ Model for Inflatable Mascot

I already have an approved mascot design and a full set of reference photos. What I now require is a clean, watertight OBJ file that my inflatable-costume manufacturer can take straight into their production workflow.

The model must faithfully match the proportions and silhouette shown in the pictures, be built at real-world scale (we will agree on the final height before you start), and be free of non-manifold edges so the factory’s pattern-generating software reads it without errors. All major color blocks should sit on separate material IDs so the vendor can quickly translate them into fabric panels; no complex textures or moving parts are needed.

Deliverables
• One production-ready OBJ file, correctly scaled and centered at world origin
• A quick viewport screenshot set confirming topology and dimensions
• Up to two small adjustment rounds to nail fit and proportion after the first preview

I work comfortably with Blender, ZBrush, or Maya files if you wish to include the original project file as a bonus, but the OBJ is the essential hand-off. Let me know your expected turnaround time and any questions about the reference images, and we can get started.
