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

thingiverse

Attaches to the Mean Well PSU using the original fan screws. One doesn't have any sound baffles, so you can keep it clear for the best airflow, or easily remix it to add your own internal noise baffle walls. The other one has 4 internal noise baffle walls, which will reduce the noise but also the airflow. Use at your own risk. I liked the design of the existing baffle for the LRS-350 by vampyrex13, but not the baffle walls. They're all straight, which isn't how a baffle is typically designed. Monkichi57's idea of extending the cover to the edge of the PSU is a good one, but not for aesthetics - it gives you more room in which to reduce the noise. Do one screw at a time. Unscrew, fit the cover, and replace. Otherwise your fan will fall off. If you want to remix it: [With baffle walls on Tinkercad](https://www.tinkercad.com/things/1at4ULV6LVW-mean-well-lrs-350-ender-3-pro-fan-cover-noise-baffle) [Hollow version on Tinkercad](https://www.tinkercad.com/things/hXN2xrdHRRV-mean-well-lrs-350-ender-3-pro-fan-cover-hollow) If you find this useful, please let me know by giving it a like.
