Ducted fan
thingiverse
This project was inspired by a Thingiverse design (http://www.thingiverse.com/thing:5756) for a ducted fan. Instead of purchasing new parts, an existing CPU fan was repurposed. The TOM_fan_duct.stl file is printable on a thing-o-matic and designed to rest on the extruder platform. By adjusting the length of the hanging arms, airflow can be controlled. Print the STL file and, ideally, find a fan that fits over the pegs. If necessary, the .prt file created in NX6 is included for editing purposes; I can also attempt to convert it into other formats upon request.
With this file you will be able to print Ducted fan with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Ducted fan.
