Dual fan top cover for Ender 3
Description
I designed this dual fan top cover for the Ender 3 to keep a 4.2.2 main board from a V2 cool enough to not have the stepper motor issues. The configuration of the main board case in the original Ender 3 is easier to cool than the Ender 3 Pro or Ender 3 V2, so I put the old board in my original Ender 3. The cover allows for 2 40mm fans to be mounted and has vent holes and separate air paths for the hot air to exit. The top holes are covered to keep debris from falling in.
