Fan Duct for Creality Ender 3 / CR10 with extra support

thingiverse

Human: Update on a fan duct modification that's perfect for parts cooling.\r\n\r\nI've taken an existing design and added a crucial feature: two mounting points instead of one.\r\nThis ensures the duct stays firmly in place from both sides, eliminating any chance of sagging or contact with the print over time.\r\nWith standard PLA printing, I'm thrilled to report no issues whatsoever.\r\n\r\nThe modification is cleverly designed to avoid support material during printing and includes a flat surface on the side, ideal for integrating automatic bed levelling sensors (ABL / BLTouch).\r\nI plan to add this feature myself soon.\r\n\r\nEnjoy!\r\n\r\nUPDATE: After a month of continuous use with standard PLA, I'm proud to say there's been no sagging or deformation whatsoever.
