Inline Turbo-Exhaust Fan For K40

thingiverse

This is an inline exhaust fan I built for my Chinese K40 Laser Engraver, as the blower that came with it wasn't blowing strong enough for my needs. It's specifically designed to work seamlessly with 5V hobby motors. The outer casing of the housing should be roughly 4 inches in diameter, allowing it to fit comfortably with standard dryer duct vent hose. I'm also considering adding an alternate file option for users who might want to use a more powerful motor. If you have any suggestions for improvements or tweaks, please feel free to leave a comment below and let me know! I've double-checked the design and made sure that it's manifold and should print without any issues. Since I haven't had a chance to print it yet, if you do decide to give it a try, please keep me posted on how it works for you!
