Ender 3 92 mm fan PSU cover (LM2596 option)
thingiverse
This is a design where the 92mm fan sits on the outside of the PSU. You'll need a metal fan cover (around 3 EUR...) to screw onto the fan as well. The LM2596 sits inside in the PSU. Use the screws that are normally provided with the fan for attaching it to the cover. You may need to turn the model around in your slicer, onto the build plate with the flat side. !!! I have printed this once only and made some small corrections afterwards - please let me know if it fits! If not, let me know what needs to be changed. Until I have enough feedback that everything is fine, I'll leave it as work in progress. !!! I've provided the FreeCAD source file as well, I used version 0.19 21514-git.
