3KU Printer Blower / Fan diffuser
thingiverse
Updated Feb 2019 for a smaller and better diffuser This enables a large airflow to be directed around 360 degrees of the hot-end and enables good bridging and fast printing. All the bolts are M3, you will need 6 x bearings to enable all the parts to move easily. Note the Spring from the elbow joint to the farthest metal support arm is important to keep the fan centered and to prevent it from twisting and generally getting caught up. Here is the fan I used: https://www.aliexpress.com/item/Free-Shipping-Original-Delta-BFB0712H-7530-DC-12V-0-36A-projector-blower-centrifugal-fan-cooling-fan/32453609963.html I hope you find this as useful as I have!
