As I needed to mount my Meanwell LRS-150-48 PSU to my VCore3 printer, I designed this mount adapter. It doesn'r require supports of printed as seen in slicer pics.
You need 3x M3 6mm BHCS bolts and one M3 heat-insert (best with 4.6mm OD and a max height of 5mm). Using SHCS Screws might interfere with the DIN rail itself, due to the higher bolt heads.
This design was inspired by the great DIN Rail bracket: https://www.printables.com/model/97222-din-rail-bracket
