Wasn't to happy with the supplied mount that's included with the Creality dual Z upgrade kit for the Ender 3.  As it pushed the PSU further out of the back of the printer and mine (printer) is pretty much up against a wall as it is. 

Decided to create a side mount for it. Best used with this (https://www.printables.com/model/158946-ender-3-psu-cover/comments/1415119) PSU bottom cover as the PSU sits on the surface the printer is on. You could try the stock bottom cover but the two screws may not be able to hold the PSU up.

You may also need to use the feet this part is remixed from to raise the printer up. Also remixed the foot into this design as I knew it just works with sliding onto the extrusion.

IMPORTANT

With this ‘mod’ you WILL need to create a wire to connect to one of the bolts on the PSU and connect it to your printer. 

THIS WILL MAKE SURE YOUR PRINTER FRAME IS GROUNDED. 

You need to make sure it's also connected to a non-powder-coated part of the frame. See the image for an example.
