⚠️ Safety First
- DE-ENERGIZE: Unplug the device from mains power before any disassembly. For battery-powered devices, remove the battery.
- MAINS VOLTAGE: If the device plugs into a wall outlet, mains voltage may be present even when the device appears "off." Capacitors can retain charge after unplugging.
- TOOLS: Use insulated tools when working near exposed circuitry.
- WORKSPACE: Work on a non-conductive surface in a well-lit area.
This guide assumes basic electronics safety knowledge. If you are unsure about any step, consult someone with experience before proceeding.
Not yet verified on hardware
Under constructionMost guides here start out this way. This one was researched and reviewed, but it was written from device specifications, vendor documentation and the design of the parts involved rather than from a unit on a bench — so the firmware versions, menu paths, print settings, part fit and timings in it are unconfirmed. Follow it, and check each one against the device in front of you as you go.
The safety steps above are standard practice and apply in full — they are not the unconfirmed part. The procedure is. Where the device differs from what this guide describes, the device is right.
Run it on real hardware? Please tell us how it went — that is how a guide gets marked verified, and a correction is every bit as useful as a confirmation. Email support42@liberatedbread.com (the subject line fills itself in), or open an issue if you would rather. Even "followed it, worked, nothing to add" is worth sending.
What You're Building
The stock Eufy Indoor Cam mount is flimsy, and a common complaint is that the pan-and-tilt mechanism works loose over a few months until the camera sags. This guide walks you through replacing it with a 3D-printed articulating wall mount — more stable, more adjustable, and entirely under your control.
This is a physical modification. No firmware changes, no software liberation — just better hardware.
Parts List
| Part | Quantity | Notes |
|---|---|---|
| PLA filament | ~15g | For the wall mount body |
| PETG filament | ~5g | For the ball joint (more flexible, won't creep under load) |
| M3×12mm screws | 2 | Stainless recommended |
| M3 nuts | 2 | Nylon lock nuts preferred |
| Wall anchors (drywall) | 2 | Standard #6 anchors |
| Wood screws | 2 | #6 × 1" |

3D Printed Parts
Articulating wall mount (PLA, 20% infill)
Ball joint connector (PETG, 50% infill)
Print settings:
- Wall mount: PLA, 0.2mm layers, 20% infill, 3 perimeters, no supports needed
- Ball joint: PETG, 0.15mm layers, 50% infill, 4 perimeters. PETG is essential here — PLA will creep under the constant load and the joint will loosen
Step 0: De-energize / Unplug
The Eufy Indoor Cam is low-voltage (5V USB), so there's no mains voltage risk inside the camera itself. But you're drilling into your wall — check for electrical wiring behind the mounting location before drilling. If you're unsure, use a stud/wire finder or mount on a stud.
- Unplug the camera's USB power cable
- Remove the camera from its existing mount
- Remove the existing mount from the wall (if any)
Assembly Guide
1. Mount the wall plate
- Hold the printed wall plate against the wall at your chosen location
- Mark the two screw holes with a pencil
- Drill pilot holes (1/8" for drywall anchors)
- Insert wall anchors and screw the plate to the wall
2. Assemble the ball joint
- Press the ball joint into the wall plate socket — it should snap in with firm pressure
- Insert the two M3 screws through the ball joint clamp
- Thread the M3 nuts loosely — you'll tighten after positioning
3. Attach the camera
- Slide the camera onto the ball joint mount (it uses the same mounting slot as the stock mount)
- Adjust the camera to your desired angle
- Tighten the M3 nuts to lock the position — don't overtighten, PETG will crack if forced
- Plug in the USB power cable
4. Test
The camera should hold position firmly. Pan and tilt it manually to verify the ball joint has full range of motion. PETG can settle slightly under a constant load, so check the screws again after 24 hours and retighten a little if needed.
Troubleshooting
Ball joint too loose
- Reprint at 55% infill (instead of 50%)
- Or add a thin rubber washer between the ball and clamp
Wall plate sags under camera weight
- Check that you used PLA with 3 perimeters — single-perimeter prints will flex
- If it still sags, reprint with 25% infill and add a small support brace underneath
Camera won't stay at desired angle
- The M3 screws may have loosened — check and retighten
- If PETG was printed too hot, it may have warped — reprint at 240°C with the part cooling fan at 50%
Going Further
This guide covers the physical mount. If you want to liberate the camera's software (RTSP streaming without the Eufy cloud), check the Eufy Cam RTSP guide (coming soon). That route locks the camera to LAN-only and streams directly to Home Assistant or Frigate.
