Improved Anet A8 Center Nozzle Fan Duct
thingiverse
**According to the comments, this no longer fits Anet A8 blowers due to a smaller blower fan opening. I'll see about uploading a second design.** This is a from scratch remodel of the "Hesine M-505, Anet A8 - Center Nozzle Fan." I needed to make a modification of the fan for a dimensional change on my printer. In the process, I attempted to make some design changes to improve airflow and decrease noise: * Thinner walls near the fan output to increase airflow and decrease noise. * Smoother channel from fan output to ring to increase airflow and decrease noise. * Large, round air holes to target air flow to near the nozzle. * Larger diameter on the ring channel to increase air flow. NOTE: At full fan speed this cooler may cause thermal runout. It's really that good! I'm able to run my fan at 60%, decreasing the overall noise and achieving terrific bridges!
