thingiverse

10-24-19 Update: Enhanced model features increased clearance within nozzle and optimized mounting holes for precise alignment toward nozzle.\r\n\r\nRecent adjustment since 10-9-19:\r\n-\Improved mounting hole clearance for added leeway in mounting higher and snugly to fan\r\n-Cut bottom of duct slightly shorter to enhance clearance and accommodate potential wiggle room from stock Ender 3 fan case, preventing excessive height\r\n\r\nEffective fan duct utilizing only the original Ender 3 components. Strategically designed vents direct airflow predominantly below nozzle at extruding plastic.\r\n\r\nEnsure not to over-tighten bottom two bolts to prevent damaging mounting holes (~half a turn after feeling resistance).\r\n\r\nTip: If fan duct rubs against emerging plastic, try loosening screws securing hot end fan case to gantry, push it upward, then tighten screws for a slightly elevated setup.\r\n\r\nYour support by liking, sharing creations, or offering tips will motivate me to create more innovative projects!
