Grandstream GWN7721 – 10-inch Rack Mount (1U)

ENGLISH

Grandstream GWN7721 – 10-inch Rack Mount (1U) for Homelab

Designed a simple rack mount for the Grandstream GWN7721, mainly because I could not find one that really matched my needs.

The GWN7721 is, in my opinion, a fantastic switch for a homelab setup:

• 8x 2.5GbE ports
• 2x 10Gb uplinks
• Relatively compact size
• Fits perfectly in a 10-inch rack
• 1U compatible

This makes it a very interesting option for compact labs, networking enthusiasts, virtualization setups, NAS + VMware environments, or anyone building a small but capable infrastructure.

The GWN7721 breathes through the side vents, and cooling is completely passive. Because of this, I intentionally added cutouts and spacing in the side brackets to improve airflow and avoid placing the switch too tightly against the mount.

It may not be the most space-optimized approach, but I preferred to leave room for ventilation and long-term reliability.

Included files

I am uploading several files so others can modify or improve the design:

• 3MF file → ready to print
• PDF with measurements → includes front panel dimensions and references
• Version 2 measurements (failed attempt) → uploaded intentionally because I made the tolerances too tight and had to make the switch fit using a Dremel 😅. Sharing mistakes can also help others.
• SolidWorks source file → for anyone who wants to adapt or improve the design

Credits & References

I am also including a 10-inch rack panel dimension reference PDF that I originally used as a baseline while designing the mount.

I honestly do not remember where I downloaded it from, but it contains the author reference, so proper credit where credit is due:

Thanks to Mikael Lindström for the original panel dimension reference used during this project.

Printing notes:
Printed in Figutech PLA Basic on a Bambu Lab A1. The first print attempt ended in spaghetti for unknown reasons, but the second attempt printed successfully without any changes.

Disclaimer / Expectations

I have not touched SolidWorks for more than 20 years (since university!), so please do not expect professional CAD-level perfection. This was a practical project made to solve a real problem in my homelab.

That said, it works, and hopefully it can save someone else some time.

If you improve it, remix it, or adapt it, feel free to share it back with the community.

Because, as someone once said:

“Human knowledge belongs to the world.”

As always, printer calibration, filament, environment, and slicer settings can affect the final result. 3D printing sometimes has a touch of black magic.
