Update: 2017-02-02 mroek designed a superior cooling fan specifically tailored for the stock CraftBot hotend. This innovative design uses an incredibly powerful blower fan for enhanced cooling efficiency, surpassing the weak cooling fans provided with the stock CraftBot hotend. I highly recommend implementing mroek's design due to its significant improvements in airflow and heat dissipation. For a customized cooling solution, use his excellent design. http://www.thingiverse.com/thing:1876044 CraftBot users should print this custom fan duct specifically designed for the stock CraftBot hotend in ABS material. This modification is particularly useful when updating or repairing existing CraftBot hotends. Update: 2015-03-23 (The initial file was inaccurately labeled. I have since uploaded the correctly leveled file, ensuring a perfect fit.) Initially, I had some reservations about the original design's low profile; however, I made two key adjustments to suit my preference – raising the fan slightly and extending the opening closer to the nozzle for optimal performance. Additionally, I provided two separate files designed specifically for the older 11mm thick fan used in a batch released in November. When utilizing this fan type, consider reducing its speed to minimize pressure on the surrounding plastic.
