Wanted something to mount my Raspberry Pi running OctoPrint out of the way at the back of the printer. See instructions for screws etc....4 x M4 x 10mm to mount bracket to PSU 4 x M3 Nuts - Push into nut traps 4 x M3 x 6mm to mount PI to bracket The PI mounting screws are tight, be careful and they will go (I did not have any M2.5's as should be used.....) OpenSCAD attached for any adjustments as required..... There is also a cable tie area on the right of the bracket to allow you to strap a UBEC / 7805 voltage converter for simple PI powering through the GPIO pins from the PSU....
