Live Wire block clamp

I do a lot of tinkering with LEDs and use an old PSU to help with the 5v/12v inputs I need and I really didn't want the live wires dangling around anymore so I came up with this. Hope it helps!I'd be more than excited if anyone can add onto it or better the design, thank you! M3*8 screws were used in the corners to clamp the top to the bottom.
