Ender 3 external case with 120mm fan
thingiverse
First thing I post here is a mashup of two other projects; https://www.thingiverse.com/thing:4106997 and https://www.thingiverse.com/thing:1595208. I added a 120mm fan to the bottom of an external control box, threw in a 120mm fan grill, and some support pieces under the motherboard mounting points. I'm not sure if these supports are actually doing anything or not. It's not perfect - I noticed that some circles were off-center. To level things out, I made some feet for the fans using material from the fan grill, so they're roughly 2mm above the surface now. I haven't printed it yet, but feel free to remix this project if you'd like.
