Laptop cable-junction hidder

My laptop's power supply unit died, so I had to pick a new one, but the cable's termination differs. So I cut the laptop's original cable, and made a junction with the new PSU. But this junction is ugly, and may break if you pull both ends of the cable.

Hence why I made this "junction-box" for computer cables. With a M2 hole in the middle.

It also acts like a "make the cable end heavier so it does not fall down all the time" thing
