Fin-mounted Fan Duct

thingiverse

This custom fan duct creator crafts a fan duct that securely attaches to a hotend featuring cooling fins, relying on the fins to maintain its position. It shows promise but requires refinement, functioning effectively in testing so far. Hotends constructed from all-metal materials paired with a small heat break tend to remain remarkably cool during standard printing temperatures, making PLA an ideal choice for printing this duct; however, more robust materials like ABS may be preferred for certain applications. Print Settings: Printer: MakerArm Rafts: No Supports: Yes Resolution: 0.2mm Infill: 100% Notes: This design should print smoothly on a well-calibrated machine. Exercise caution against common printing pitfalls. It's better to err on the side of over-extrusion and then adjust as needed. A thin wall can be effective, especially with supports in place.
