A set of easy-to-use, lightweight, and flexible cooling duct systems with a variety of adaptive accessories. Simply install the top clips under the radial fans, and you can quickly attach and remove various accessories by sliding them into place. The operation is convenient and efficient.

When printing, it is recommended to set up only support structures on the build plate to ensure the stable formation of the bridging area. For the single air duct design, it is only necessary to add a small amount of support at the bottom to effectively support the bridge deck, without the need to add additional support inside the air duct.

When designing these components, I iterated and optimized them multiple times and used PLA material for printing. During the process of continuously updating and improving the model, I used the previously printed old-version models to provide cooling support for the new parts. After testing, these old-version models did not melt or warp under the heat radiation of the high-temperature nozzle. In addition, since there is always cold air circulating in the air duct, using PLA material generally does not cause any problems. However, to be on the safe side, it is still recommended to choose PETG or A

The bottom of the double-air duct may be slightly rough due to the supporting structure, but it can be easily repaired and smoothed with a file or sandpaper.
