I’m currently running five different SBCs (3 Raspberry Pis and 2 Rock64 boards), each hosting different services. The current setup has turned into a wiring mess and is also affecting cooling.

To clean things up and save space, I’m planning to build or 3D‑print a rack that allows for better organization and airflow. I’ve searched online for existing 3D printable designs, but I haven’t found anything that fits my needs.

I’m hoping someone here can help or point me in the right direction.

Requirements:

• Space to mount 6–7 SBCs (with some extra room for future expansion)
• Two of the SBCs have 2.5‑inch HDDs attached, so I’d like mounting space for those as well
• Proper cable‑routing space for Ethernet and USB cables
• Space to mount an extension board

Any suggestions, designs, or guidance would be greatly appreciated. Thanks!
