Made a simple adapter for Mean Well LRS-150F-48 PSU to mount on Unifi US-16-150W original psu stands.

I took the countersink screws from the original psu´s heatsink and bolted the adapter with and the original mounting screws to screw the new psu into the adapter. So no screws needed.

I resolder new cables to the PSU before i had the PSU so thats why my cables are a bit long. And i think the original cables are to short so you probably need to extend them or resolder them.
From the PSU i just cut off the original cable connection and putted ring terminals on, also made an extra earth cable from the psu and bolted it with adapter to one of the stands in.

Printed the adapter with PETG
