Inline Duct Fan
thingiverse
I built this as an in-line booster fan to pair with my bitcoin miner exhaust setup so the main fans don't have to work as hard, hopefully reducing noise levels somewhat.\r\n\r\nDesigned to work seamlessly with 3 inch flexible ducting from Home Depot or similar, and the piece that attaches to the 120mm fan on my Antminer S9 is available at https://www.thingiverse.com/thing:3630788\r\n\r\nBefore printing, ensure your printer is dimensionally accurate because the 60mm by 38mm fan is press-fit. It's simply a 60mm computer fan from a Dell Power-Edge 2950 server.
