Description
One-piece pealess whistle, modeled from published dimensions. Overall 45 x 20 x 12 mm. Key dimensions: chamber diameter 16 mm; chamber height 8 mm; window width 10 mm; labium tip height 8.6 mm; lanyard hole 4 mm; print in place true. Original solid CAD modeled from scratch. Closed meshes and digital clearances are checked; physical printing and load/flow performance have not been tested. Use millimeter units for STL. Single solid with enclosed resonator, narrow windway, top window, sharpened labium and lanyard eye. No assembly or loose pea is required. Print flat without internal supports; the chamber roof is a bridge. Sound and air-jet behavior have not been tested physically. This is an original geometric whistle prototype, not a certified signaling device. Watertight STL mesh in millimeters, ready to slice; printed performance is untested. Export to other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.
