Jayhawk 2.5 inch 073236 — Revision B — ESTIMATED
Source identity: CURRENT_073236

This free pack preserves the original STL and STEP geometry from the expanded
Estes Nose Cone Library B. All geometry is in millimeters.

Base diameter: 63.50 mm
Exposed height including features: 215.90 mm (excludes shoulder)
Shoulder: 61.47 mm diameter x 63.50 mm long
Overall X x Y x Z: 63.50 x 63.50 x 279.40 mm
Evidence confidence: low. This is not a numerical tolerance.

These models use educated estimates, including inferred dimensions and shapes.
They are solid exterior references for CAD editing, not verified replicas or
finished hollow flight parts. No printer clearance, original hollow interiors,
electronics or recovery hardware are included. Solid CAD does not prescribe
100% slicer infill. Digital geometry checks do not validate physical fit, mass,
strength or flight suitability. Check actual tubes and print fit yourself.

Why this shape was chosen:
Official diameter 2.5 in controls scale. The straight manufacturer photo gives exposed length about 3.4 diameters and shoulder about one diameter. Adopt 8.5 in exposed and 2.5 in shoulder; borrow the 61.468 mm shoulder diameter from the related PSII 72413 reference as a fit estimate. The narrow longitudinal raised detail visible midway on the front side is represented by a small blended fairing; exact ridge cross-section is uncertain.

Estimated fields:
- exposed_length_mm
- profile_stations
- shoulder_diameter_mm
- shoulder_length_mm
- feature_dimensions
