Egg Capsule nose portion, BT-65 030110 — Revision B — ESTIMATED
Source identity: CURRENT_030110

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: 45.62 mm
Exposed height including features: 154.00 mm (excludes shoulder)
Shoulder: 44.45 mm diameter x 25.40 mm long
Overall X x Y x Z: 45.62 x 45.62 x 179.40 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:
The Green Eggs instructions identify 030110 as the combined molded nose H and adapter I that are cut apart. Model only the nose portion after that cut; the rear adapter is not another nose. The photographed exposed part is roughly 3.4 base diameters. Borrow 45.6184 mm outside diameter and 44.45 mm shoulder diameter from the historic BNC-65L reference as nominal fit estimates; adopt 154 mm exposed length and a 25.4 mm shoulder. Official Green Eggs diameter is rounded 1.8 in / 46 mm.

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