Mean Well LRS-350 (Ender 3 Pro) Fan Cover (Noise Baffler and Hollow options)

thingiverse

Attaches fan to Mean Well PSU using original screws. One doesn't have sound baffles so keep clear for best airflow or easily modify to add your own internal noise baffle walls. The other one has 4 internal noise baffle walls which reduce the noise but also airflow. Use at your own risk. I liked design of existing baffle for LRS-350 by vampyrex13, but not baffle walls. They're all straight, which isn't how a baffle is typically designed. Monkichi57's idea of extending cover to PSU edge is good one, but not for aesthetics - it gives more room to reduce the noise. Do screw at a time. Unscrew, fit cover, and replace. Otherwise your fan will fall off.
