Prompt
Create a fully functional pea whistle keychain designed for real-world FDM 3D printing and commercial sale. The model MUST clearly resemble a real referee whistle with proper acoustic geometry. 🔷 Core Shape Requirements (VERY IMPORTANT) Classic referee whistle profile Visible mouthpiece air channel (rectangular slot) Proper whistle window (sound opening) on the side Circular pea chamber (hollow ball cavity) inside Flat bottom edge for stable printing Smooth aerodynamic top curve ❗ Do NOT create toy blocks or abstract shapes. ❗ Must look like a real sports whistle. 🔷 Branding Add raised embossed text: TVK Position: centered on the circular chamber face Font: bold sans-serif Text height: 0.8–1.2 mm raised Clean readable spacing 🔷 Keychain Hook (Strong Requirement) Integrated reinforced loop at rear Inner diameter: 5–6 mm minimum Outer thickness: ≥2.5 mm Rounded fillets for strength Must be part of the body (not floating) 🔷 Color Reference (from provided image) Main body: matte red plastic Accent stripes: bright yellow Yellow ring around chamber Yellow stripe along top of mouthpiece Two-tone clean separation 🔷 Functional Engineering Constraints Minimum wall thickness: 2.2 mm Air channel must be hollow and continuous Pea chamber must be hollow sphere cavity Overhangs ≤ 45 degrees No trapped geometry Watertight manifold mesh Print-ready without heavy supports Optimized for FDM printing 🔷 Size Total length: 65 mm Chamber diameter: ~24–26 mm Keychain loop suitable for standard key ring 🔷 Output Quality High-resolution smooth mesh Real-world scale in millimeters Origin centered Export formats: STL and STEP Commercial product quality 🚫 Negative Prompt (IMPORTANT — include this) low poly, toy whistle, blocky, abstract shape, solid interior, non functional, missing air channel, missing whistle window, broken mesh, thin walls, sharp edges, decorative only Create a high-quality, production-ready 3D printable whistle keychain inspired by the reference image. Design requirements: * Style: modern plastic whistle with smooth rounded edges * Body shape: classic pea whistle form with circular air chamber and extended mouthpiece * Branding text: raised embossed text **"TVK"** on the round chamber face * Text style: bold, clean sans-serif, slightly extruded (not engraved) * Color scheme: * Main body: matte red * Accent stripes: bright yellow bands around the chamber and along the top of the mouthpiece * Include a **built-in keychain hook loop** at the rear: * Strong reinforced ring * Sized to fit standard keychain rings (≈5 mm inner diameter minimum) * Smooth rounded edges for durability * Surface finish: slightly matte plastic suitable for FDM printing * Wall thickness: minimum 2–2.5 mm for strength * Internal whistle mechanism: * Functional air channel * Pea chamber hollow inside * Designed to be printable without complex supports * Print optimization: * Oriented for easy FDM printing * No extreme overhangs beyond 45° * Watertight manifold mesh * Clean topology * Output scale: * Length: ~60–70 mm * Width proportional to standard whistle size * File output: **STL and STEP ready** Quality requirements: * High-detail but print-efficient * No sharp edges * No non-manifold geometry * Commercial product quality suitable for selling * Centered origin and proper real-world scale in millimeters --- ### 🔥 Optional (if your generator supports negative prompts) **Negative prompt:** low poly, rough mesh, thin walls, broken geometry, non-manifold, sharp edges, text engraved, asymmetrical, toy-like proportions, excessive supports
