6 Inch inline duct fan cover

Fan guard for  6 Inch (150mm) Inline Fan duct fans was built for the “fan guard for TerraBloom 6 Inch (150mm) Inline Fan” sold on amazon but would probably work for others. 

This would be useful if you aren't using the duct connection on both sides and would like to add a guard to it. 

8/2/2024 Modified design to get rid of inner tabs as they can break off easily. 

Remember this is a 3d printed item and might not provide the same level of protection as a manufactured guard. It also could possibly restrict some airflow.  If you do use this, you are using it at your own risk. 

Prints without supports, featuring a 6mm hole on the side to accommodate a 4mm threaded insert, allowing for the use of a 4mm screw for retention in case of looseness.
