Release gates
  • No physical prototype measurements are present; empirical validation remains deferred.
  • V5 candidate files, OpenSCAD starter, vector review plates, print packet, and authority registers are committed.
  • SolidWorks source CAD exists, but no browser-renderable GLB/glTF export is committed for model-viewer.
  • Flue/labium and side air-tube delivery measurements are required before any shop release.
  • Cultural attribution should be reviewed before public promotion.

01 · OverviewFujara Studio Explorer

fujara — concept render

The fujara is a Slovak overtone shepherd's flute from the Podpolanie region; this repository documents Tony Koop's engineering derivation and does not claim cultural ownership of the tradition.

Scope & provenance

Pattern: Parametric stave-built fujara study with SolidWorks source CAD, acoustic/capstone analysis, and deferred physical validation. Public-domain status: Engineering files are CC-BY 4.0; cultural/music practice requires respectful attribution. The fujara is a Slovak overtone shepherd's flute from the Podpolanie region; this repository documents Tony Koop's engineering derivation and does not claim cultural ownership of the tradition.

Model-viewer asset needed

Source CAD exists, but no browser-renderable .glb or .gltf was found yet. Export the chosen SolidWorks assembly into the repo's CAD folder and rerun this generator; the explorer will then inline small .glb files automatically.

Readiness boundary

This page is a root-level studio guide over existing repository evidence. It is not a fabrication release by itself: dimensions remain governed by the design-table workbooks, SolidWorks references, and capstone CSV outputs, while physical tuning and overblow validation still require a built fujara.

Design authority
Parametric workbooksFundamentals from D2 through F#3, A2 capstone baseline, and G2 SolidWorks dimensions.
