10-Inch 1U Dual Hot-Swap Rack Mount Caddy for Radxa X4 SBC - 3D Printable STL & 3MF Files | Custom Design for Homelab Clusters

Craft Your Own Dual Radxa X4 Rack Mount with These High-Resolution 3D Files!**

Streamline your homelab with this 3D-printable 1U rack mount caddy designed for Radxa X4 SBCs, compatible with the same 58mm x 49mm mounting hole pattern as the Raspberry Pi 4 and 5 Model B. This digital file set includes separate high-resolution STL and 3MF files for the main frame and individual caddies, optimized for FDM printing on most 220x220mm beds. The slide-in caddy design incorporates spring-loaded retention clips for secure positioning and an embossed handle with a tactile indent for easy removal, enabling hot-swapping without tools. Printed in durable ABS, the open-frame structure with honeycomb venting ensures optimal airflow, while cable management slots support zip-tying looms or bottom routing for standard USB-C cables—avoiding kinking issues common in cramped mounts.

File Details & Print Specifications:
- File Formats: High-resolution STL and 3MF files (frame and caddies separately) for seamless slicing in Cura, PrusaSlicer, or Bambu Studio—ideal for custom tweaks in Fusion 360 or Blender.
- Print Orientation: Lay frame and caddies rack face down on the bed to customize front panel texture (e.g., PEI, carbon fibre) and appearance, enhancing homelab aesthetics.
- Strength Optimization: Use 8-10 wall/perimeter count for maximum durability in ABS, avoiding infill delays; designed with optimal wall thicknesses for solid-like strength. Print time: 4-6 hours per unit at 0.2mm layer height, 0.4mm nozzle, ~200-300g material.
- Compatibility: Fits standard 10-inch mini racks (e.g., Project Mini Rack) with precise mounting holes, occupying 1U (1.75 inches) for shallow-depth builds under 300mm.

Applications & Use Cases in 2025 Homelab Trends:
Harness the Radxa X4’s Rockchip RK3588 octa-core SoC (up to 2.4GHz) for Kubernetes or Docker Swarm clusters, edge computing nodes for IoT data, or AI inference with TensorFlow Lite. Build Pi-Hole ad blockers, OpenMediaVault NAS, Home Assistant hubs, Proxmox VE virtualization, Plex streamers, or industrial automation nodes. The hot-swap feature supports maintenance in high-availability setups like robotics prototypes or web hosting, aligning with sustainable, low-PUE trends amid self-hosted AI growth.

Benefits for DIY Homelab Projects:
This design addresses overheating and cable strain in dense 1U mounts, offering airflow and accessibility. Print at home to save on shipping, customize materials (ABS for heat resistance, PETG for eco-friendliness), and scale clusters affordably (under 5W idle per X4). Ideal for apartment or garage homelabs bridging to hybrid cooling solutions.
