Mosquito hotend fan duct with guide vane mod for BLV MGN Cube 3d printer
thingiverse
A quick mod from original fan duct design by shadewind. https://www.thingiverse.com/thing:3985383 I add simple vane to improve the airflow, noticeable difference compared to the original one. It's not the most optimized design by any mean, but it works quite well. Based somewhat on this video guide by Alex Kenis. https://www.youtube.com/watch?v=SX-okOHvh1Q Also, I add a sacrificial bridge layer into the countersunk bolt hole so you can print without support when print finish just drills out the hole with M3 drill bit.
