Ender 3 and Pro Hot End Baffle
thingiverse
This custom baffle fits snugly outside the Ender 3 Pro housing, potentially compatible with other Creality models that utilize the same enclosure. It's recommended to use PETG for optimal results, as PLA may cause deformation and over time, the piece will no longer remain securely in place due to the loss of springiness in the clips. This baffle performs a decent job of silencing the hot end fan and preventing debris from entering the fan blades. In fact, I've tried using a filter before, but it resulted in reduced airflow below what's required for proper hot end operation.
