Ender 3 power supply bracket modified

The original design by mlynch002 fit the 4040 extrusion just fine but the holes on the design didn't line up with the stock (non-Meanwell) power supply on my Ender 3. I attribute this to variations in the manufacturers design of the power supply. I simply modified the size and location of the slotted screw holes. I used an M4 screw on the left side and an M3 screw on the right.
