Mean Well LRS-350-12 mounting for 3030 extrusions

This is a remix of stonediggers great Mean Well LRS-350-12 mounting. Compared to the original it is intended to be used with 3030 aluminum extrusions and designed so that it is mounted onto and not in the corner made out of the extrusions.

I modified the original design since I wanted to mount the LRS-350-12 onto my new Hypercube Evolution and mounting the PSU like in the original design would probably led to collisions with the heated bed.

The mounting is compatible with the Rocker Switch
