The Sidewinder X1 has a basic fan duct that works well, but the cooling is done only from one side. I wanted to improve this and because i am using a BLTouch with the Waggster Mod, there were limited options i could choose.
So, the improved Fan Duct was born.
After installing the improved fan duct, part cooling works better and cooling is done from 180 degrees.
The improved fan duct can be downloaded from Thingiverse.
