This project provides STL files for a simple enclosure that holds multiple Orange Pi Zero 3 boards in a compact cluster.

It's designed to be easy to print, assemble, and scale while keeping ports accessible and cables manageable.

Features

• Horizontally stackable design for 2+ Orange Pi Zero 3 boards.
• Passive airflow through side openings — no fans required.
• Access to all ports, except header pins.
• No screws needed for board mounting — friction fit.
• Cable and antenna clips for tidy wiring.
• Compact footprint.
• Easy to print on standard 3D printers.
• Customizable for different board counts.
• Open-source and freely available.
• Lightweight and durable.

Assembly

1. Print all the parts.
2. Glue cable and antenna management clips to the sides.
3. Insert Orange Pi Zero 3 boards into the slots.
4. Put the top cover on.
5. Connect power and network cables — cluster ready.
