Ultimaker 2 Compact Fan Duct

thingiverse

I designed fan ducts with a simple, open layout that allows for easy maintenance of the hot end. Perfect for users who frequently swap nozzles or use the Olsson block. They are also ideal for compact 3D printer builds. As an owner of a 3D printer, I sought to create a design that is both space-efficient and provides unobstructed access to the hot end for servicing. Since I don't often run my fans at full capacity, excessive cooling wasn't a top priority, but these ducts should still be sufficient for most enthusiasts. Included with this project are single STL files and an all-in-one print, making it easy to start printing right away. To complete your setup, simply acquire 4 M3x8mm screws. I also strengthened the hanging points to minimize the risk of cracking, a common issue found in printed fan ducts. When mounting my fans, I only needed two screws and that's all it took to keep them securely in place. Please note that this design is considered a work-in-progress for the next 30 days as adjustments may still be made to refine its performance. Print Settings Rafts: No specific settings apply. Supports: Optional; it ultimately depends on your specific printer requirements. Infill: A moderate 30% infill rate worked well in this case. I used ColorFabb PLA for printing these ducts, adding a brim layer for added stability. When testing my prints with proximity to the heat source, I didn't experience any issues with warping or deformed print quality.
