3D Printable Model of Collapsible Vuvuzela trumpet

I need a detailed and functional 3D printable model of a vuvuzela (a South African trumpet) that is collapsible and telescopic in design. The model will consist of three parts that must print in place, interconnected, and fully functional without additional assembly. This vuvuzela must be intended for actual use (playing), so precision is critical.

You will receive a reference image of the desired product along with as many dimensions as possible. The deliverable should be optimized for 3D printing with PLA (Polylactic Acid), ensuring ease of expansion and collapse, strong interconnection between sections, and compactness when fully collapsed.

Experience in designing 3D models that are specifically optimized for printing is essential. Please provide proof of your prior work creating 3D-printable designs. The final output must include a fully tested, print-ready file that ensures functionality as described.

Looking forward to collaborating with a skilled designer who can successfully bring this design from concept to printing reality!
