1U Blank Modular Rack Mount for 19” Network Rack

1U Modular Blank Panel for 19” Network Rack

I designed this modular blank panel for standard 19-inch network cabinets to cover empty rack spaces while maintaining a clean and professional look.

This model follows the 19” rack standard (1U) and is designed as a two-piece modular panel. By printing and assembling two mirrored parts, you can create a complete 1U blanking panel for your rack.

I printed the model in PETG, a material that offers excellent mechanical and thermal resistance — ideal for environments where temperatures may rise. The design is sturdy, lightweight, and optimized for 3D printing, with mounting holes aligned for standard rack installation.

Features

• Standard 19” rack compatible (1U)
• Two-piece modular design
• Clean and professional appearance
• Easy to print and assemble
• Strong and durable structure
• Perfect for covering unused rack spaces

Assembly

To assemble the complete panel you will need:

• 3x M5 screws (minimum screw length: 14 mm)
• 3x M5 nuts

Once the two halves are connected, the panel can be mounted directly to the rack using:

• 4x M6 rack screws with cage nuts/inserts

No modifications are required — simply assemble the two printed parts and mount the panel to the rack rails.

Printing Notes

• Recommended material: PETG
• PLA can also be used for light-duty applications
• Print orientation as provided in the model files for best strength

You can pair this panel with other rack accessories from the same category, such as:

• Unifi Switch 8 PoE Lite
• Unifi UCG Max/Ultra

I also created a 2U version, available on my profile.
