Tronxy X3 Part cooling fan duct.

This system allows a 40mm blower fan to be perfectly fitted onto the Tronxy X3 FDM printer. Its design leverages the identical mounting holes found on the hot end shroud, providing a seamless integration. To secure it in place, simply use short lengths of threaded rod or grub screws in replacement of the existing screws, using stand-offs instead. You might need to adjust the holes slightly using a drill or file for a perfect fit. The recommended print settings include utilizing a heat-resistant material like PETG, and you'll want to set your nozzle size to 0.4mm, coupled with a 0.2 layer height for optimal results. Happy printing!
