# RemoteRig Hardware Design Pipeline > Living queue for 3D-printed / physical hardware design work. ## Active / Ready for CAD prototype ### Camera node case v4 — upright status panel + strap mount **Status:** Parametric OpenSCAD source created; body/lid/preview STLs exported and validated watertight. Ready for CAD review, exact part measurement, and first prototype print. **Files:** - `hardware/case/camera-node-case-v4.scad` - `hardware/case/camera-node-case-v4-body.scad` - `hardware/case/camera-node-case-v4-lid.scad` - `hardware/case/camera-node-case-v4-preview.scad` - `hardware/case/camera-node-case-v4-front-review.scad` - `hardware/case/camera-node-case-v4-body.stl` - `hardware/case/camera-node-case-v4-lid.stl` - `hardware/case/camera-node-case-v4-preview.stl` - `hardware/case/camera-node-case-v4-front-review.stl` **Design direction:** - Stand-mounted upright camera node enclosure; the case still does **not** mount to the GoPro. - Visual direction now matches the original green appliance-style reference: tall vertical body, large inset front panel, centered OLED near the upper third, blank middle area, two long rounded lower slots, bottom USB-C female power input, right-side USB-A female passthrough power port for the GoPro, and left-side IPEX/U.FL antenna pigtail/connector exit opposite the USB-A. - This replaces the rejected wide/low generic electronics-box layout from the first v4 attempt. - Primary mounting is reusable cloth zip ties / Velcro straps through two low-profile vertical rear brackets with long lateral side-feed openings, not a clamp/dovetail. - Front has a recessed/flush full-height service lid similar to a field-service status panel. - Lid includes cutouts for: - 1.3-inch OLED/status screen. - separate 3 mm power LED. - single 3 mm RGB status LED replacing red/green status LEDs. - small rocker on/off switch. - two long rounded lower front slots styled after the reference. - Front-panel screen, LED, rocker, and lower-slot openings are actual through-cuts through the full lid and locating lip so the back side of the printed lid is not skinned over. - Body includes screw bosses, recessed lid pocket, lid locating geometry, a bottom USB-C female power inlet cutout, a right-side USB-A female passthrough power cutout, a left-side 5.0 mm prototype IPEX/U.FL antenna pigtail/connector through-hole with shallow exterior recess, and two vertical external rear zip-tie/Velcro brackets to resist rotation on a stand. The zip ties feed laterally through long side windows behind the raised bridge faces; the old top-to-bottom feed-through tunnel is intentionally closed by top/bottom anchor pads. - Internal envelope is sized for known module dimensions plus service clearance: - ESP32-C3 Super Mini: 22.5 × 18 mm. - ESP-01S: ~24.7 × 14.3 × 12 mm. **Prototype display content target:** ```text CAM 03 REC ● BAT 87% LINK OK 00:12:34 ``` **Prototype dimensions to validate before production:** - Exact 1.3-inch OLED module dimensions: - PCB width/height/thickness. - active display/window width/height. - connector side and ribbon/header clearance. - mounting-hole positions, if using module screws or adhesive tape. - Rocker switch: - snap-in cutout width/height. - bezel/flange size. - required panel thickness range. - rear depth and terminal clearance. - LEDs: - preferred holder/bezel style, if any. - final hole diameter for 3 mm PWR LED and 3 mm RGB STAT LED. - current-limiting resistor placement. - Wiring/service: - USB cable diameter and bend radius. - bottom USB-C female panel/breakout connector flange, body depth, and mounting requirements. - right-side USB-A female panel/breakout connector flange, body depth, and mounting requirements for GoPro 5 V passthrough. - left-side IPEX/U.FL antenna pigtail/bulkhead exact outside diameter, retention/flange needs, bend radius, strain relief, and whether the current 5.0 mm prototype through-hole plus 8.5 mm shallow exterior recess should change before production. - actual regulator/power distribution board footprint if used. - Fasteners: - M2 vs M2.5 vs self-tapping screws for lid. - pilot diameter, screw length, and head/counterbore diameter. - Mounting straps: - cloth zip-tie / Velcro width and thickness. - prototype rear side-feed opening: ~40 mm long vertical side window × ~3.8 mm strap-thickness clearance behind each raised bridge, with each visible vertical bracket ~8.5 mm wide × 50 mm tall. - whether two strap paths are enough to prevent case rotation on the expected stand diameter. - whether rear vertical bracket/window edges need larger radii or TPU/silicone sleeve protection. - Printability: - rear vertical zip-tie bracket top/bottom anchor-pad and bridge strength, and whether the lateral side-feed openings print cleanly without supports. - body/lid fit after PETG shrinkage. - lid lip clearance and screw boss robustness. - USB-C/USB-A and IPEX antenna exit cutout edge quality, wall strength, and connector retention/strain relief. **Suggested OpenSCAD validation/export commands:** ```bash openscad -o /tmp/camera-node-case-v4-body.stl hardware/case/camera-node-case-v4-body.scad openscad -o /tmp/camera-node-case-v4-lid.stl hardware/case/camera-node-case-v4-lid.scad openscad -o /tmp/camera-node-case-v4-preview.stl hardware/case/camera-node-case-v4-preview.scad openscad -o /tmp/camera-node-case-v4-front-review.stl hardware/case/camera-node-case-v4-front-review.scad ``` Latest validation: OpenSCAD reports `Simple: yes`; trimesh confirms body, lid, preview, and front-review STLs are watertight. Body and lid each export as a single connected printable component; preview includes separate non-print board/connector guide volumes by design. A rear-bracket sanity check confirms both vertical brackets have clear non-solid lateral X-direction side-feed volumes behind the raised bridge faces, while the rear wall, bridge faces, and top/bottom anchor pads remain solid. The left-side IPEX/U.FL antenna hole is a through-wall cut to the interior cavity, not a blind exterior pocket. Or with the main parametric selector: ```bash openscad -D 'part="body"' -o /tmp/camera-node-case-v4-body.stl hardware/case/camera-node-case-v4.scad openscad -D 'part="lid"' -o /tmp/camera-node-case-v4-lid.stl hardware/case/camera-node-case-v4.scad openscad -D 'part="preview"' -o /tmp/camera-node-case-v4-preview.stl hardware/case/camera-node-case-v4.scad openscad -D 'part="front_review"' -o /tmp/camera-node-case-v4-front-review.stl hardware/case/camera-node-case-v4.scad ``` ## Prior prototype reference ### Tripod electronics case v3 **Status:** Historical design reference. In this checkout, previous v3 SCAD/STL files are not present; v4 starts a new `hardware/case/` CAD source set. **Previous design notes:** - Held ESP32 + ESP8266 stack. - Screw-on lid with vent slots. - Rear dovetail-style rail/socket interface. - Separate screw-tightened tripod clamp sized around a 35 mm stand/pole. - Clamp used M3 hardware: one M3 screw across the clamp mouth, with an M3 nut trap. **Reasons superseded by v4:** - User requested front status/service panel with OLED, LEDs, and rocker switch. - Single RGB status LED replaces separate red/green status LEDs. - Rear strap pass-through loops are simpler and more adaptable than a dedicated clamp/dovetail for field stands. ## Backlog ### 10.1-inch touchscreen + Raspberry Pi Zero case **Status:** Specific display identified; mechanical measurements needed before CAD. **Goal:** A printable enclosure for the RemoteRig hub/control panel using a 10.1-inch touchscreen and Raspberry Pi Zero / Zero 2 W. **Display target:** - Vendor/model: HZWDONE Raspberry Pi Screen 10.1" Touchscreen - Resolution: 1024×600 - Interface: HDMI portable monitor - Mounting: includes fixing holes - Compatibility listing: Raspberry Pi 5/4/3B/B+ and Windows 11/10/8 **Initial assumptions to validate:** - Compute: Raspberry Pi Zero / Zero 2 W mounted behind or below the display. - Use case: RemoteRig local monitor/control panel at field recording setup. - Likely needs: front bezel, rear electronics cavity, Pi mounting posts, HDMI/USB/power cable exits, strain relief, ventilation, and optional tripod/stand mounting. - Because this is a 10.1" panel, design should prioritize rigidity: thicker bezel ribs, rear standoffs, and possibly a two-piece shell instead of a small snap case. **Required measurements before CAD:** - Product link or datasheet for the exact HZWDONE 10.1" variant. - Screen/PCB outer dimensions: width, height, thickness. - Active display opening dimensions. - Fixing-hole locations, hole diameter, and screw size. - Connector locations/orientation for HDMI, USB touch, and power. - Whether the driver/controller board is integrated with the display PCB or separate. - Pi Zero orientation, port access requirements, and whether GPIO/header must remain accessible. - Power connector position and desired cable routing. - Mounting preference: desktop kickstand, tripod clamp, VESA-style holes, handle, or combination. **Proposed design approach:** 1. Create `hardware/display-case/`. 2. Build a parametric OpenSCAD model with measured display/Pi dimensions. 3. Split into printable parts: front bezel, rear shell, Pi/controller tray, optional stand/tripod mount. 4. Validate STLs with OpenSCAD + trimesh. 5. Upload generated STL/SCAD artifacts to Seafile.
