Ender 3 closed fan shroud (improved filament cooling)
thingiverse
Ender 3 closed shroud for improved cooling where main fan blows under nozzle just like nozzle fan. (I combined few designs from other people to modify and combine them to closed shroud) Layer height: 0.2 PLA 1) Backplate- no support 2) fan shroud- support needed 3) nozzle duct- no support Whole "model" file is not for print, just for you to check how it looks. I used rubber main fan holder insted of screws so consider to find suitable ones if needed. (stock ones will not fit for main fan, you can use stock screws only for nozzle fan)
