This 3D-printable enclosure is designed for anyone building a DIY wireless head-tracking system based on Cliff’s (dlktdr) excellent open-source project:
https://headtracker.gitbook.io/

The system uses an Arduino Nano BLE 33 and a standard RC receiver to create a lightweight, low-latency head tracker for FPV or RC applications. For a clear walkthrough on setting it up wirelessly, check out AndyRC’s great tutorial:

Why This Enclosure?
This design provides more internal space for your RC receiver compared to other cases, making wiring and positioning far easier. It also securely locks in a USB-C to Micro USB adapter, preventing strain on the Arduino board.

The enclosure prints in two parts and includes two top-shell options:
- LED Window Variant – features a cutout for visual feedback from the Arduino and receiver. Print the window in translucent filament.
- Solid Top Variant – clean exterior with no LED visibility.

This model only covers the enclosure system. A dedicated goggle mounting solution is not included yet. However, both STEP files and the Fusion 360 project file (.f3d) are included for easy remixing and customization.

If you improve or adapt it, please share your remix. I’d love to see what you build!
