X2 drop in Duct

thingiverse

This duct is designed for the X2, without any change, just remove the original one and insert this one (it's a tight fit on purpose, does not require any glue). Should slightly improve the prints quality and/or allow faster print speeds. Preferably print using PETG to avoid problems. I can make a more heat resistant version if asked, but PETG works very fine for me. I didn't do serious benchmarks yet but it can probably be improved more, the .blend file is provided so you can tweak it to your taste using Blender3D.
