Super_pommels_and_flag rotating flagpole finial v0.7.6

Super_pommels_and_flag is an experimental rotating flagpole-finial project combining printable PETG/TPU mechanics, a 12 V illuminated fish flag, ESP32-C3 firmware, BLE control, a local Android application, and an offline component, drawing, and 3D catalog.

The current cumulative engineering handoff is v0.7.6. All 23 canonical printable parts are generated as native build123d/OCP B-Reps rather than copied from transitional meshes. This revision adds captive M4/M3 nuts to every current screw joint, uses a closed twin-bore flag-power guide angled about 35° downward on the lower rounding of #petg-2, shortens the VEML7700 light tunnel to 15 mm with a dedicated glue land, adapts the AHT20+BMP280 pocket to a 20 mm adhesive membrane with a 10 mm active centre and seven ventilation holes, and adds a removable two-level electronics carrier.

Rigid parts target the already purchased orange PETG. TPU 95A is used for retained functional soft parts and TPU 85A for static seals. ASA remains a possible future reprint. This is not a production-ready or safety-certified product: purchased-part fits, outdoor durability, sealing, thermal behaviour, wiring, BLE, and structural strength still require physical validation.

Repository areas

• mechanical/ — current parametric model generator, 40 validated STL files, seven current GLB files, drawings, previews, and validation data;
• electronics/ — current wiring drawings and ESP32-C3 firmware;
• android/ — local BLE control application prototype;
• catalog/ — generated offline catalog whose sources include components.json, the single physical-measurement registry physical-components.json, and drawings.json;
• docs/ — current status, design rationale, audits, and immutable ADR history;
• scripts/, tools/quality/, and tests/ — reproducibility and repository checks.

Stable filenames containing v0_6 are retained for compatibility, but their current generated content is version 0.7.6.

The canonical printable source is mechanical/generate_build123d_canonical_v076.py and the native STEP/report output is stored in mechanical/build123d_v076/. Legacy reference drawings and non-print interactive scenes keep their existing generators and are regenerated only when the owner explicitly requests them.

Local component, drawing, and 3D catalog

Run from the repository root on Windows:

powershell -ExecutionPolicy Bypass -File .\tools\windows\open-component-catalog.ps1

The script binds a local server to 127.0.0.1, opens catalog/catalog.html, and enables interactive GLB viewing. Stop it with Ctrl+C.

To open the catalog explicitly in Firefox:

powershell -ExecutionPolicy Bypass -File .\tools\windows\open-component-catalog.ps1 -Browser Firefox

Regeneration and checks

Run the complete model, drawing, catalog and validation pipeline from the synchronized antivirus-safe worktree:

.\build.cmd all

The generate, validate, and catalog modes are also available. Large *.stl and *.glb files use Git LFS; PNG remains in regular Git. GitHub Actions downloads LFS only for the conditional mechanical job.

The checks validate repository consistency and STL topology. They do not establish a verified IP rating, safe load, fit, temperature, lifetime, or correct operation on real hardware.
