A printable reimagining of the wooden Kidsbox: rectangular cabinet with two front speakers, removable top lid (NFC tag rests there, reader mounts beneath), and swappable speaker mounts. - kidsbox.scad: master model + part dispatcher (body/lid/speaker_adapter/grill) - params.scad: all tunable dimensions in one place - lib.scad: helper modules (rounded shell, bosses, bolt circles) - Fixed front-panel speaker interface + swappable adapter so any driver fits by printing a new adapter (edit spk_* params, re-export) - Internal mounts: 2x18650 cradle, ESP32-LyraT standoffs, RC522 under lid, 3 buttons on lid, USB/charge + power-switch side ports, back-wall vents - Snap-in speaker grills - Makefile to export STLs and render previews (headless via xvfb) - Exported STLs and preview renders included - Link enclosure from main README Dimensions are sensible defaults from the reference photos and common parts; README flags the fit-critical values to verify before mass-printing. https://claude.ai/code/session_01MhAnh68DPNnTjcKqjNYDmk
