K40 Exhaust Duct for 3" Blower

thingiverse

This is a custom exhaust duct designed for use with a 3-inch blower, which replaces the standard fan that comes equipped with the K40 laser cutter. The exhaust duct is split into two parts due to its size; however, I have also included a single-part version for those who have access to a large enough printer to create it in one piece. This design was created specifically to interface with this blower: https://www.amazon.com/gp/product/B001O0DE9E/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1, but other 3-inch blowers should work just as well with it.
