Ender 3 Power Supply Upper Clip
thingiverse
During initial assembly, the top screw for the power supply stripped out. I went straight to OnShape.com and threw together a clip that slides down the extrusion channels and clips into one of the holes on the far side of the power supply. The fit is rather snug so there is no wiggle unless you purposefully try to move it. Making the lug on the small arm a little longer to grab in the hole better or using a small strip of double sided tape would make this a seriously permanent fix.
