Dual fan cooling duct V5 for Flashforge Creator/Replicator dual

thingiverse

I've uploaded a brand new version (v6) with specially designed ribs that prevent the bottom from warping or distorting in any way. This latest update is based on my previous duct design, which was heavily influenced by MasterFX's pioneering work in this area. To take it to the next level, I've made some significant changes: a larger slot for increased airflow, a more horizontal bottom, and an overall sleeker look that's sure to impress. The screw holes are cleverly covered with a thin layer of material, making it easy to pierce through with a single screw - you'll only need two screws, so I've intentionally left the other holes open. No supports are required for printing, thanks to the duct's clever design. What's more, this duct clips securely onto the extruder assembly without any fasteners whatsoever. The single fan provides a beautiful curtain of air flowing across the print, and adding another fan or a larger one would actually serve no useful purpose because there's still a significant restriction - the area of the slot is smaller than the area of the fan. These "muffin" fans are designed to move a volume of air, not build up pressure. That's why they're not as effective in applications where pressure is needed. In contrast, heavier blower-type fans are better suited for building pressure. There are many impressive fan ducts out there on Thingiverse, and I've taken inspiration from some of the best ones. However, I've designed this particular duct to make better use of the muffin fan's abilities - it's a more efficient design that's sure to please even the most discerning users. How I came up with this design is a story in itself. I used Autodesk Fusion 360 to redraw and refine my ideas, taking them from concept to reality in record time.
