Optional vent blockers designed for use with my ventilated 6-inch 3U rack side panel.
When active ventilation is installed, open vents can allow air to take a shorter path around the equipment instead of flowing through the intended cooling area. These blockers close selected openings and help create a more focused airflow tunnel through the rack.
The blockers are optional and should be installed according to the position of the fans, equipment and desired airflow direction.
The two files cover different vent areas and can be used individually or together, depending on the cooling configuration.
Printing recommendations
Material: PLA or PETG
PETG is recommended for warmer rack environments
Print the blockers flat on the build plate
Supports: not required
Important airflow note
These parts are intended for racks with planned active ventilation. Blocking vents without providing sufficient fan-driven airflow may increase equipment temperatures. Monitor temperatures after installation and remove or reposition blockers if cooling performance becomes worse.
