This project is a DIY 3D-printed XR Neckband designed as a single U-shaped piece that balances batteries, devices, and cables comfortably around your shoulders.
The neckband acts as a universal hub for XR glasses. As an alternative to needing a proprietary accessory, you can connect small streaming or computing devices directly into your USB-C XR glasses — including Viture One, XReal Air/Air 2, Rokid Max/Air, and Lenovo XR glasses.
I’m a huge fan of smart wearables, AR/VR, mixed reality, and especially XR glasses. I’ve personally tested models from XReal, Rokid, Viture, and Lenovo, and this project reflects that interest in tech innovation.
My hope is that this open-source, sharable model will help promote growth in the XR glasses market segment by encouraging remix, experimentation, and community-driven innovation — especially using components like the Raspberry Pi with accessible GPIO ports for adding sensors, cameras, or other creative mods.
Commercial XR docks and hubs can be expensive, often with limited compatibility. I wanted something low-cost, flexible, and modular that anyone could print and use. Along the way, I focused on a few main goals:
1. Affordability – Use 3D printing + low-cost components.
2. Multiple device support – Works with your choice of Amazon Fire Stick, Microsoft Miracast Adapter, or Raspberry Pi Zero 2W.
3. Battery life – Dual 5000mAh batteries keep things running longer.
4. Customization – Ability to add external components such as cameras, sensors, or even tap into Raspberry Pi GPIO ports.
5. Comfort – Lightweight build with ergonomic distribution.
⚙️ Features- All-in-one U-shaped design with battery holders built in.
- Dual battery support for longer runtime.
- USB-C cable clip (top-left placement) for XR glasses connection.
- Cable channels integrated on both left & right arms for clean management.
- 3D-printed TPU comfort layer designed for neck comfort.
- Customizable filament & color options (PETG and TPU recommended)
- Remix-friendly CAD files for personal tweaks and mods.
These components were tested and verified with the ModuBandXR design.

🔮 Future ModsThis neckband is open-source and remix-friendly. Here are a few potential mods that myself or you can explore...
External Cameras – Add front-facing POV cams.
GPIO-powered sensors – Use Raspberry Pi GPIO pins to add modules such as a momentary push button to activate a a camera.
Computer Vision – Try OpenCV for object detection.
Voice + AI – Add a mic for hands-free AI interaction, similar to Meta smart glasses.
[Component cables / ribbons can be hidden inside the left / right cable tracks]

👤 About the Creator
This project was designed and created by #IamLoveless, a DIY tech enthusiast exploring affordable XR solutions and experimenting with AI for brainstorming new ideas, building projects, and testing out the limits of AI.
✨ I was also looking for a summer professional development project that applied design thinking, combining creativity, prototyping, and problem-solving into a meaningful build.
