This is a custom shroud that easily mounts via existing threaded holes found on the bottom of the internal case (top of the power supply compartment).
This shroud covers the exposed pins and connections on the lower edge of the installed motherboard.
Easily install using 4 x M3 x 5mm HDD/case screws that came with the case.
Printed using Black PLA filament inverted on it's top face with supports for the 4 tabs.
It seems my print shown has some roughness around the tabs due to the supports, however you may be able to improve your print quality by making adjustments as needed.
Note: The threaded holes may only be available on newer models of the Corsair 4000D AirFlow RGB case. My case was purchased in December 2024 and has the threaded holes available. I've found that on a 4000D AirFlow case purchased in July 2022 does not have the threaded holes.
The author marked this model as their own original creation.
