Velleman PSU mod for extra terminals

I have a simple 13.5V PSU from Velleman, works OK and seems it has low RF noise. But it only has one connection terminal, 4 mm banana plugs. I started looking for a terminal connection board but the prices was very high.

So I did a very simple mod, I just drilled two holes in the front panel and mounted two extra 4mm banana plus and connected internal to the same connections points.
