v0.4.0-alpha — fuller coverage and pad-retention prototype

v0.4.0-alpha — fuller coverage and compliant-pad seats

Physically unvalidated prototype / work in progress. The opening has been
checked digitally, not tested on a printed cover or real AirPods. Do not treat
the release as frictionless, self-retaining, load-rated or production-ready.

Changes from v03

• Fuller rear body/lid wrapping with shaped hinge-motion relief.
• Bounded front window and separate USB-C / ANC-speaker openings.
• Five seats for separately supplied soft retention pads: two body sides,
  two lid sides and one roof. Bare rigid shells remain unretained.
• Initial 0.80 mm soft-foam trial thickness; final thickness, compression,
  finish compatibility and any removable roof adhesive need physical testing.
• Preserved Clawd silhouette, rear pixel branding, diagonal 4 mm keyring bore
  and outer dimensions.

Checks and files

• Both printable meshes are watertight single components with positive volume.
• 116 sampled hinge poses from 0–115° pass the calibrated-surrogate collision
  screen, including illustrative seated pads. This does not simulate friction.
• A clean build from the included credited references reproduces both STLs
  byte-for-byte with Blender 5.2.1 LTS.
• Source ZIP includes the sanitized editable Blender model, build tools,
  parameters, renders, digital QA and older v03 artifacts. Restricted donor
  meshes and private workspace material are excluded.
• Print one body and one lid, either the two STLs or the two-object 3MF,
  at 100% scale in millimetres. Pads and ring are separate hardware, not prints.
• Read docs/PRINTING.md and docs/QUALIFICATION.md before ordering.

GitHub is the canonical v04 source. Printables and Sketchfab still list v03;
the Thingiverse v03 draft remains separate until its update is verified.
