Anycubic i3 Mega UltraBase fan duct for stepper drivers (Remix)

thingiverse

Update: V2 for Cura users - Since manual support placement is not possible, this version incorporates built-in struts within the fan duct's neck, allowing the entire item to be printed without supports. These struts can easily be snapped off with pliers after printing. This remix of juha_j's fan duct (which utilizes the Noctua 40x40x10mm silent fan NF-A4x10 FLX) has undergone several modifications: 1. The duct walls have been thickened for enhanced rigidity. 2. The "neck" of the fan holder has been slanted to achieve a more streamlined airflow, as suggested in cannon3d's comment. 3. The duct has been lengthened and a fixing collar added at the end, expelling hot air directly through the metal base's ventilation holes. The .skp files (in Sketchup 2018) are included for anyone wishing to make improvements.
