Ender 3/PRO PSU relocation bracket

thingiverse

I needed a bracket to set the PSU back on my printer to make room for a dual Z screw upgrade. I wanted it to be as simple as possible. This mounts using four M4x8 screws with T nuts. The fifth hole is used to make a ground connection which was eliminated when the PSU was relocated. For the ground, I used a wire connected to the AC ground wire in the wiring box and attached a screw lug to the free end. I then used a T nut and an M4x12 screw with a couple of washers under the head to allow the tip of the screw to make solid contact with the extrusion and be tightened to the bottom of the bracket at the same time. One of the mount holes could be used for this purpose as well. The row of holes in the bottom was an afterthought for allowing ventilation air out of the PSU. I added holes in the .stl file after I printed my copy. The three mounting screws on the side and back are M4x8.
