Remixed Hot End Fan Mount with Metal Bosses

thingiverse

I replaced a faulty fan blade with a Noctua, deciding that the reliability of this new component was essential for my system's stability. Initially, I had been running a Fang, but I encountered issues with its mount loosening over time. This problem arose because it is practically impossible to achieve sufficient tension in the screws when tightening onto plastic material. To rectify this situation, I designed and fabricated metal bosses that could be screwed into place. Using 7mm OD aluminum stock, I cut out cylindrical bodies with 3mm IDs and a thickness of 5mm. These components were then securely attached to the fan's mounting bracket using epoxy. I am confident that this modification will resolve any future issues related to loose mounts.
