Mean Well LRS Power Supply Fan Plate

thingiverse

This is a two-piece top plate for the popular Mean Well LRS DC power supplies. The Top Plate includes a custom cover for the end of the supply, allowing airflow, wire connections, and access to the adjustment screw. The Fan Plate is designed to mount a 120 mm case fan securely, which makes the power supply much quieter and cooler than the tiny stock fan! I included screw tabs for the four stock side screws, but these might not work well since PLA doesn't have any flex. I recommend attaching the top with electrical tape. The same is true for the case fan: I suggest using those rubber "pins" rather than steel screws, though they should work too. I also suggest using a little window screen material on the top of the fan to keep fingers and junk from falling in. Note that the power connector on the Mean Well power supply is different from stock but is easy to modify. Once you swap the wires, the 120 mm fan works great, powering on with load.
