V-Core 3 120x38mm Static Cooling fan mount

This is a static cooling fan if you think the toolhead cooling is not powerful enough or wanting to reduce toolhead weight. This duct is made for Delta PFR1212DHE, but it should work on any standard 120x38mm fan. It can be mounted to 3030 aluminum extrusion with 12mm M6 bolts and T nuts and the fan can be mounted with the universal self-tapping PC fan screws.
