Build ANY Size Server Rack... From Your 3D Printer!

Published at : 23 Dec 2025

Want to 3D print a server rack of any size? Stop buying or printing rigid, single-purpose solutions!

After searching for a truly scalable and universal rack system, I gave up and developed my own:

HomeRacker

It's a fully modular, parametric, 3D-printable system that lets you build anything—from a simple Raspberry Pi cluster rack to a full-blown 19-inch monster or even Gridfinity drawers and custom shelves!

In this video, I walk you through:
* The problem with current printable rack solutions.
* The core components and simple mechanics of the HomeRacker system.
* A look at the growing ecosystem of extensions (shelves, airflow kits, Pi cases, and more).
* Real-life builds including the Mini Pi Rack, a 19" prototype, my flagship Cyberpunk 10" Rack, and... The Abomination!

The best part? It's open-source and free! Let's rack 'em all!
