Description

On 2026-10-24 the owner asked for the Air Hub Mini schematic, PCB and 3D views including the enclosure ("开始做原理图pcb和3d图包含外壳"). The schematic and the routed revision D board already exist. This task adds an enclosure concept and 3D renders, made the same way as the Air Hub Pro enclosure concept, with Mini-only tooling under tools/mini/enclosure/:

Board model: board_boxes.py writes board_mini.scad, one box per footprint, with data-sheet heights for the Mini parts.
Enclosure: air_hub_mini_enclosure.scad is a PC/ABS V-0 base and lid with gasket and corner screws (IP54 target). USB-C exits through the back wall and the M8 panel socket through the left wall. The lid carries light pipes for SYS and RADIO and a silicone PAIR key. Both antennas sit under plastic.
Render script: render_enclosure.sh writes four views and base and lid STL files to air-hub-mini/enclosure/.

Acceptance criteria:

Renders: the assembled, exploded and open-base views show the board, connectors, light pipes and key at their PCB positions.
STL: base and lid STL files are exported.
Docs: the reference board §7.4 shows the 3D board view and the enclosure views; the Mini README lists enclosure/.
Quality gate: bun run docs:lint && bun run docs:build && git diff --check passes.

Notes

Results (2026-10-24):

Outline: about 97 × 86 × 24 mm, without the corner lobes and mounting flanges.
Clearance: the inner height above the board is 14.4 mm. The tallest part is the 47 µF / 100 V electrolytic at 10.5 mm. The board stands on 3 mm M3 standoffs, since there are no bottom-side parts.
Open:
- The vertical JST XH header with a mated plug and leads comes close to the lid. A side-entry S4B-XH-A is the better choice for the hand layout.
- The M8 socket order code, gasket material and USB-C production part are still open (AIR-O-04).
- This is a concept model, not a tooling drawing.
