Dual 40mm Fan: Reprap Guru

thingiverse

After testing several different designs, none seemed to take into account the need for filament changing. I designed these specifically with that in mind, making it easier to swap out filament as well as completely remove them if you need to work on the nozzle. 25May2018 I noticed warping occurring with the bracket holding the fans - most likely due to using PLA - so I modified it to be slightly thicker. I'm also working on a new version of the fans, which will be uploaded once they're finished. 10Jun2019 I finally got around to uploading the new fan version, which features a slightly bigger opening for air to flow out.
