I noticed that the plastic part of the Ender3 PSU only attaches via 2 screws on the side of the unit. This allows that plastic portion to droop under it's weight. This annoyed me, so I created this simple spacer (with a hex pattern, of course) that slides into the horizontal (foot) extrusion and support the PSU

You must temporarily remove the PSU from where it mounts to the upright leg in order to slide the spacer onto the extrusion, as the wires coming out the bottom of the PSU will block it's path
