Creality CR-10s Pro Fan Duct easy printing and more secure

thingiverse

This is a modified version of the OEM Creality CR-10s Pro fan duct. The original design features an extremely thin tab that attaches to the fan, which breaks easily under stress. To address this issue, the tab has been thickened for added durability. Additionally, the bottom of the duct was previously slanted, causing problems with printing quality. To resolve this, the bottom surface has been flattened to make it easier to print with. Beyond these changes, there have been no modifications made to improve airflow or uniformity. However, the original fan works effectively in cooling the nozzle and filament for successful bridging. This modification provides a more accessible option for those who prefer to use the basic stock version. The bolt used to attach the duct can be reused with some adjustments or replaced with a slightly longer 25mm bolt for better grip. I find that M3x25 bolts work perfectly in this application.
