Portal Turret - CoralBoard SL Modular Enclosure

A serviceable CoralBoard SL enclosure in the form of a Portal sentry turret, with a camera eye, audio, manually deployable wings and a removable electronics cassette. WHAT MAKES IT PRACTICAL • Two removable baskets for complete modules up to 25 × 20 × 7.6 mm, with common printed lids, a locking key and optional reducer frames. • Internal cable channels and keepers, accessible rear terminals and a flush service hatch. • Manual telescopic wings: 32 mm travel per side. Eye gimbal limits: pan ±6°, tilt ±5°. • Optional desk dock, six-compartment tray, and a three-channel cable comb. The accessories require no additional purchased fasteners. FILES AND DOCUMENTATION 33 core STL types, 34 required printed pieces; P23/P24/P33 are printed twice. P12/P13 are unused; P34/P35 are optional reducers. The upload also includes three optional desk accessories and 12 fit-test pieces, for 48 STL files in total. Editable Fusion and STEP, illustrated 45-page assembly manuals in English and Polish, electrical and programming guides, KiCad schematic/PCB/Gerbers, host software, CircuitPython firmware and a simulation mode are included. Extract both Print_and_Build and Editable_CAD archives into the same directory to combine the complete folder structure. ADDITIONAL HARDWARE CoralBoard SL; one 608ZZ bearing; three formed Ø5.6 mm aluminium leg rods; one Ø8 × 1 mm aluminium tube axis; three feet cut from 3 mm sheet; two positional micro servos; a USB/UVC camera within the 15 × 15 × 13 mm allocation; an 8-ohm speaker within Ø28 × 5.5 mm; XIAO RP2040 Standard, MAX98357A amplifier, controller PCB E2, two Ø3 mm red LEDs and suitable wiring/connectors. An optional fan fits 25 × 25 × 7 mm. M2/M3 fasteners, foam, straps and adhesive are detailed in Hardware_BOM.csv and the assembly manuals. Some base-mechanism M3 lengths and servo linkage require dry fitting. The base system uses wired 5 V power with separate positive supply rails for CoralBoard and actuators and a shared ground. Battery/charger spaces are unconnected reserves. Wings are manual; software tracking controls the eye only. Check the electrical guide before connecting hardware. PRINT AND ASSEMBLE Print fit coupons first. Suggested starting point: PETG, 0.4 mm nozzle, 0.16 mm layers; follow the per-part wall/infill settings and orientations in the tables. For the optional A01 dock: 0.20 mm layers, five walls, 25% infill and a 3 mm brim on a 350 mm bed. Minimum strength/fit settings have not been established by physical tests. Parts carry physical IDs matched to the BOM and assembly steps. PROTOTYPE STATUS Digitally checked CAD/electronics prototype, not yet fully printed, fabricated or commissioned. Confirm purchased component dimensions, physical fit, snap durability, stability, cable movement and electrical operation on the first build. The cover is a stylized CAD visualization, not a photograph of a completed print. GIFs present the CAD parts and assembly sequence.

POLSKI Serwisowalna obudowa CoralBoard SL z kamerą w oku, głośnikiem i ręcznie rozkładanymi skrzydłami. Wyjmowana kaseta elektroniki, dwa koszyki modułów, kanały kablowe i dopasowany tylny terminal ułatwiają montaż i serwis. Opcjonalna podstawa ma wsuwaną tackę oraz klips kablowy. Zacznij od instrukcji montażu PL i próbek pasowania. Pakiet zawiera również polskie instrukcje elektryki, programowania i akcesoriów oraz tabele części i ustawień druku. To prototyp sprawdzony cyfrowo; pełny wydruk i uruchomienie wymagają jeszcze próby fizycznej. Skrzydła są ręczne, zasilanie bazowe przewodowe 5 V, akumulator i ładowarka pozostają niepodłączoną rezerwą.
